SOLUTIONS FOR DATA INTERPRETATION REPLICA QUESTIONS THAT HAVE APPEARED IN CAT IN THE LAST 4 YEARS

TABLES

Solutions for questions 1 to 3: 1. Let the volume of data transfer in India and Singapore

be 100 units each. Revenue from data transfer in India = 100 × 1 = $100 Revenue from data transfer in Singapore = 100 × 9 = $900

Total revenue in India = 100 × 9

100 = $1111

Total revenue in Singapore = 900 × =21

100$4285

∴Total revenue in Singapore is about 4 times that in India. Choice (5)

2. Revenue from data transfer as a percentage of total

revenue for India in 2010 = 27% Revenue from data transfer as a percentage of total

revenue for Sweden in 2010 = 36% Let total revenue in India in 2010 be $200 and that in

Sweden be $100 ARDT of Sweden = $6

∴Volume of data transfer in Sweden = 66

36 =

∴Volume of data transfer in India = 6

∴ARDT in India = 96

54 =

∴ The percentage increase = 1001

19 ×−= 800%

Choice (3) 3. It can be seen that if the total revenue received is the

same for the given pairs of countries, only UK and Spain would have approximately the same volume of data transfer. Choice (4)

Solutions for questions 4 to 6: 4. To get calls from all the colleges, Arun should have

scored at least the highest value of cut-off in each section, i.e., 44 + 44 + 45 + 44 = 177 and also at least the highest value of aggregate cut-off for any institute, i.e., 176. Choice (2)

5. The minimum aggregate marks to get calls from two

colleges is 171. If he scores 50 each in three sections he needs to score at least 21 marks in the fourth section. Choice (3)

6. Four colleges have a cut-off for section C and the

remaining two colleges have a cut-off for section D. ∴ If a student misses the cut-off in these two sections,

he/she would miss calls from all the colleges. The maximum possible marks such a student gets is 50 + 50 + 40 + 42 = 182. Choice (3)

Solutions for questions 7 to 9: 7. The new gross pay of the employee transferred

= 16,000 + 10080 × 16000 = 16,000 + 12,800 = 28,800

The gross pay of the current employees in HR department = 16000 × 5 = 80000

New gross pay of the six employees = 80,000 + 28,800 = 1,08,800

Average gross pay = 181336

Finance department increase by one, it means that the age of the person who came from the Marketing department was 20 years older than the age of the person who was transferred from the Finance department. Now after the transfer of the employee to the HR department, as the average age of the employees left in the Marketing department remained the same, the age of the employee transferred to the HR department, was 20 years younger than the average age, i.e., 36 – 20 = 16 years.

The percentage change = 12.5% Choice (2) Solutions for questions 10 to 13: 10. The drink must contain 10% minerals. As there are only

two drinks (A and C) with 10% minerals, the drink can be prepared in only one way. As A and C have 30% protein each, they can be mixed to form the drink. Choice (1)

11. None of the choices (1), (2) and (3) can be used to form

the drink with 10% fat and at least 30% protein. For C and E to form the drink with 10% fat and at least 30% protein, if they are mixed in the ratio x : y (say)

Similarly the ratio for D and E is 1 : 3 and the cost per

unit is 4

800= 200

∴ The cost per unit is the least for C and E. Choice (4) 12. The drink should have at least 60% carbohydrate.

Further in the mixture formed by B, C and E, the proportion of B should be maximum and the other two should be minimum to get the lowest per unit cost. Among the given options only Choice (2) and (5) satisfy the condition having 60% carbohydrate and of these, choice (5) has the lowest per unit cost. Choice (5)

13. A and B when mixed in equal proportions, the protein

content will be only 2

less than required. Similarly B and E and C and D when mixed in equal proportion the combination will have less than the required percentage of minerals and carbohydrate respectively. Only A and E when mixed in equal proportion would yield a mixture with all the contents in the required amount. Choice (5)

Solutions for questions 14 to 17:

14. If one observes the values given for the different parameters, the values that were varying with production, i.e., value was increasing when production increased and value decreasing when production decreased are material, labour and operating cost of machines. All the remaining costs, i.e., rent of building, consumables, rates and taxes, repair and maintenance expense and selling and marketing expenses are fixed. Hence, there will be no change in these costs. The total fixed cost = 1800 + 600 + 1200 + 8700 + 2100 = 14400 The cost/unit for different variable costs is as follows. Material = `50 per unit. Labour = `20 per unit Operating cost of machine = `30 per unit Total = `100 per unit Selling price per unit = `125 per unit

Total cost/unit for 2100 units is `100 + 2100

14400

= `107 Choice (2)

15. For one product, Selling price = `125 Variable cost = `100 _________________ Difference = `25 _________________

Now, to avoid loss, the company has to offset the fixed cost (i.e., 14400) for which it has to produce a total of

25

14400= 576 units. Choice (3)

16. The reduction in selling price per unit = 5% of 125 = 6.25

New selling price = 118.75 Total fixed costs = `14400 Variable cost per unit = `100

Now the total profit increases with the increase in number of units sold and the maximum profit is obtained when the company sells and 3000 units. Choice (5)

17. The given condition is that if the company sells upto 2100 units, the selling price per unit is `125 and if the company sells 2550 units, the selling price per unit for all the units is `120. The profit of the company increases upto a production figure of 2100 units, from the 2100th unit to the 2101st unit, the total profit decreases drastically and from the 2101st unit to the 2550th unit, the profit again increases.

Hence, the profit would be maximum at the production figure of 2100 units or at 2550 units.

Production 2100 units 2550 units Selling price / unit (s) `125 `120 Variable cost / unit (v) `100 `100 S – V `25 `20

(S – V) production 25 × 2100 = 52500

20 × 2550 = 51000

Total fixed cost 14400 14400 Total profit 38100 36600

The maximum profit is `38100 Choice (1)

Department Total Male Post graduates Marketing 80 48 32 Accounts 80 44 40

Production 640 288 352 Total 800 380 424

27. Percentage of male employees in the production

department = 640

288 × 100 = 45 Choice (2)

28. Post graduates in the marketing department = 32

Male postgraduates = 10025 × 32 = 8

∴ Female post graduates = 32 – 8 = 24 Male non post graduates = 48 – 8 = 40 Required difference = 40 – 24 = 16 Choice (5)

29. Percentage of male post graduates in the marketing

department = 80

32 × 100 = 40 Choice (1)

30. The number of male post graduates in the production

department = 144. ∴ Female post graduates = 352 – 144 = 208 The number of male and female post graduates and male and female employees who are not post graduates are as follows.

Post graduate Non Post graduates

Required percentage = %200100500

5001500 =×−

Choice (C) 2. Cost when 200 units are produced = `6500

Cost when 350 units are produced ≃ `10,000

Additional cost /unit = 1503500

1506500000,10 =−

= `23.

Choice (B) Solutions for questions 3 and 4: The energy consumption of Geyser in a week is 7 kWh and we know the family uses the Geyser for 2 hrs in a day. Hence for 14 hrs in a week the energy consumption is 7 kWh. Hence the energy consumption of a Geyser per day is 1 kWh. Now, energy consumption of Refrigerator in a week is 14 kWh and the family uses Refrigerator throughout the day. Hence, the energy consumption of Refrigeration per day is 2 kWh. Similarly the energy consumption for TV in a day is 2 kWh. The energy consumption for Washing machine in a day is

74

kWh and for Grinder is 71

kWh

3. (a) Energy consumed by TV for 3 days = 6 kWh.

Energy consumed by Refrigerator for 3 days = 6 kWh. Hence Choice (1) is false.

(b) Energy consumed by Geyser for 4 days = 4 kWh. Energy consumed by Grinder for 7 days = 1 kWh.

Hence Choice (2) is false. (c) Energy consumed by Washing Machine in a week

= 4 kWh. Energy consumed by Geyser for 2 weeks = 14 kWh. Hence Choice (3) is true.

(d) Energy consumed by TV for 2 days = 4 kWh. Energy consumed by Washing machine for one week = 4 kWh Hence (d) is false Choice (3)

4. The fixed cost increased by 25 %. Hence the new fixed

cost is `60 + 41

DATA SUFFICIENCY Solutions for questions 1 to 4: 1. From A, as 60% of the newly joined employees were

not managers, the remaining 40% of the newly joined employees were managers. It is given that 10 managers had newly joined. ∴ 40% = 10 ⇒ 100% = 25 Hence, A alone is sufficient. B gives no data, it is just an assumption. Choice (1)

2. From A and the given condition, either Babu or David

got the highest rank. Hence, A alone is not sufficient.

Page 11: Di Replica Last4years Sol

11

From B and the given condition, either David or Amar can be the highest ranker. Hence, B alone is not sufficient. Combining A and B, David must get the highest rank. Choice (4)

3. It is given that, 30% of the students are boys, which

implies 70% of the students are girls. Also 10% of the girls are athletes. ⇒ 10% (70%) = 7% of the students are female athletes.

From A, 25% of the students are athletes Hence 25 − 7 = 18% of the students are boys who are athletes. So, A alone is sufficient. From B,

Number of boys who are athletes = 120% of the girls who are athletes. As 7% of the students are girls who are athletes, 120% (7%) = 8.4% of the students are boys who are athletes. So, B alone is also sufficient. Choice (3)

4. Clearly, A alone is not sufficient, as we do not know

how many points the opponent scored. B alone is also not sufficient, as we do not know how many points team A scored. Combing A and B, If the score at the half time was say 0-25, then the match would have ended in a tie at 35-35. So, team A did not win. Had the score at half time been, say, 10-35, then in the end it would have been 45-35 and team A would have won. So, we cannot answer the question even after combining both the statements. Choice (5)

PPL

1. Let the cost of the new car be `x.

Therefore the cost of the old car = 40% (x) =52

x.

From statement Ι, we cannot answer the question as neither the cost of the new car nor the cost of the old car is given. Statement Ι alone is not sufficient. From statement ΙΙ, we only know regarding his personal saving but nothing about the cost of the cars. Statement ΙΙ alone is not sufficient. By combining both the statements, we have the following information.

Now, it is not known that 25

personal savings balance. Thus the question cannot be answered even by combining both the statements. Choice (4)

(Numbers)

1. From statement A,

xy = 18 the different possibilities are: 1×18 2 × 9 3 × 6

Again yz = 21 the different possibilities are 1 × 21 3 × 7

But we do not know if x , y, z are natural numbers or not. For eg if y = 9, we can get.

xy = 18 as 2×9 and yz = 21 as 9 × 37

There will be infinite possibilities like this, so statement A is not sufficient. Statement B above is also not sufficient as it gives information regarding x and z only and nothing about y. Combining both the statements, we can conclude that x = 6, y = 3 and z = 7. Thus z is the maximum.

2. Using statement A alone we have SEVEN = 19 and FIVE = 14, without knowing anything about the values of individual alphabets, we cannot answer the question. Using both the statements together we can conclude that 2 (N) + I + E = 7 ⇒ N = 1 and I and E are 2and 3 or 3 and 2 So F + V = 14 – 5 9. F and V could be 4, 5 or 5,4. SEVEN = 19 If E = 2 and V = 5, we get S = 9 whereas if E – 3 and V = 5, we get S = 7. So we cannot determine S uniquely. Thus the question cannot be answered even by combining both the statements.

3. The number of days that Raju's dad goes to the Shiva

temple in a year is

3365

= 121 days.

The number of days that Raju's dad goes to the

Venkateshwara temple is

4365

= 91 days.

The number of days that Raju's dad goes to the

Saibaba temple is

7365

= 52 days.

The number of days that Raju's dad goes to both the

Shiva and the Venkateshwara temple is

12365

= 30 days. The number of days that Raju's dad goes to both the

Venkateshwara and the Saibaba temple is

28365

= 13 days. The number of days that Raju's dad goes to both the

Shiva and the Saibaba temple is

21365

= 17 days.

The number of days he goes to all the three temples is

84365

= 4 days.

Hence the number of days Raju's dad goes to exactly one temple is 121 + 91 + 52 – 30 – 13 – 17 – 4 = 204 days. Choice (1)

4. A + B +C + C + D + E +E +F + G = A + B + C + D + E

Now 28 + C +E = 33. ∴C + E = 5

C, E could be (1, 4), (4, 1) (2, 3) OR (3, 2)there are four possible ordered pairs of (C, E). Choice (3)

yellow coloured building is Violet. Choice (4) 2. The second tallest building is either B or D. Choice (5) 3. The colour of the tallest building is Indigo.

Choice (2) Solutions for questions 4 to 7: Stage Ι As P, Q, S and T won at least one match, R and U lost all the three matches. As Q, S and T lost at least one match, P won all the three matches. In stage-Ι, there are a total of 9 matches and so 9 wins. Q, S and T won two matches each. As P (the top team in stage-Ι) did not play against U, P played matches against Q and R. ∴The ninth match was between Q and U. So the nine matches that have taken place are as follows.

Won Lost Won Lost Won Lost P S S R S U Q T T R T U P Q P R Q U

Stage-ΙΙ As each team played a total of five matches, in stage ΙΙ, the matches take place between the following pairs of teams. P – T, P – U, Q – R, Q – S, T – S and R – U Given that, in stage-ΙΙ, three teams lost all the two matches. Given P lost both the matches in stage-ΙΙ ∴Each of T and U won the two matches. ⇒ R and S lost the two matches. ∴Q also won two matches. 4. T and U defeated P (the top team in stage-Ι) Choice (2) 5. Only Q, T and U won both their matches in stage-ΙΙ. Choice (4) 6. S and U won exactly two matches in the event. Choice (5) 7. Q and T won exactly four matches each in the event.

Choice (5)

Solutions for questions 8 to 12: The trading pattern followed by each of the three traders is as follows

Anand Bala Chandu Buy Sell Buy Sell Buy Sell

10 a.m. 3 p.m. 10 a.m., 3 p.m. 10 a.m., 3 p.m.

11 a.m., 11 a.m.,

12 noon, 12 noon,

1 p.m., 2 p.m. 1 p.m.,

2 p.m.

8. As the direction of the price movement is not known,

the profits of Bala and Chandu depends upon the prices at which they bought gold i.e., if they buy at lesser price than that bought by Anand, their profits would be more, if not, the profits of Anand would be more than that of the other two. Hence the answer cannot be determined. Choice (5)

9. Anand buys the entire quantity at a single point of time,

whereas each of the other persons buy once every hour. As the direction of movement of gold is not given, we cannot compare the returns of Anand with the other two persons.

Bala: Bala buys the same quantity of gold every time, irrespective of the price.

Chandu: Chandu spends the same amount every time, his buying depends on the price of gold at the time he buys. The more the price, the lesser quantity he buys. As his strategy is based on prices, whenever the prices are changing, Chandu’s returns will be more than that of Bala. But if there is no change in the price of gold the returns of Bala and Chandu would be equal. Hence no conclusion can be made. Choice (5)

10. On a boom day, the price of gold keeps rising, hence it

will be the least in the morning. Hence, Anand who bought all his holdings in the morning will get the maximum profit. Between the remaining two, Bala bought the same quantity at every time, i.e he bought the same quantity even at higher prices whereas Chandu spent the same amount. Hence, Chandu bought less quantity of gold when prices were high and more when prices were less. Hence, Chandu’s returns are more than that of Bala's. Bala will have the least returns. Choice (1)

Let the prices of gold at different timings be as follows.

Time 10 a.m. 11 a.m. 12 noon 1 p.m. 2 p.m. 3 p.m. Price a b c d e f

We will look at the additional information given: The quantity bought by Anand at 10 a.m. is the same as the quantity he sold at 3 p.m. As it is given that Anand lost money, we can ignore the quantity bought/sold and can conclude that the price at 3 p.m. must be less than that at 10 a.m. ⇒ a > f → (Ι) Similarly the quantity of gold bought/sold by Emma in each instance is the same and it is given that Emma made a profit. Hence we can conclude that (c + f) > (a + d) → (ΙΙ) Also using similar logic in case of David, we conclude that (d + e + f) > (a + b + c) → (ΙΙΙ) It is given that the price increased from 2 p.m. to 3 p.m. ⇒ e < f → (ΙV) It is given that price at 12 noon was lower than the opening price ⇒ c < a → (V) From (i) and (ΙΙ) we can conclude that c > d → (VΙ) From (Ι), (ΙΙΙ) and (VΙ) we conclude that e > b → (VΙΙ) Hence a > f > e > b and a > c > d ⇒ a is the highest.

11. The price of gold was the highest at 10 a.m. Choice (1) 12. As d < c, choice (4) is also necessarily false. Choice (4) Solutions for questions 13 to 15: 13. The different possibilities in which they could have

booked the rooms are as follows. Case Ι:

101 102 103 104 A C D B

Case ΙΙ:

101 102 103 104 B D C A

Since B booked an odd numbered room, we can conclude that as per case ΙΙ, B must have booked room number 101, in which case C would have booked room number 103. Choice (C)

14. It is given that two girls failed in the examination. Now

we have six possibilities in which we can select the two girls who failed. They are as follows:

Cases ↓ Dolly Molly Polly Kelly

1 Pass Pass Fail Fail 2 Pass Fail Pass Fail 3 Pass Fail Fail Pass 4 Fail Pass Pass Fail 5 Fail Pass Fail Pass 6 Fail Fail Pass Pass

Let us denote a true statement by T and a false statement by L (lie)

Cases→ 1 2 3 4 5 6

Dolly T T T L L L Molly L L L L T L Polly T T L L T T Kelly T L T T L T

As exactly three of them were telling the truth, only in case Ι it is so. Thus Molly was the person who was lying. Choice (B)

15.

It is given that n = O g = 37.5% of (a + b + c)

i.e., g = 8

3(a + b + c)

Let (a + b + c) be 8k. ∴ g = 3k Students who did not opt for Finance = b + f + c

Students who opted for Finance = a + e + d + g. (a + e + d + g) 50% = b + f + c. → (1) Students who did not opt for HR = a + e + b.

a + e + d + g = 4

5(a + e + b). → (2)

Again number of students who opted for only Finance and Marketing was 331/3% of those who opted for all three Number of students who opted for only Marketing and HR = Number of students who opted for only Finance and Marketing.

∴ f = e = 3

1g.

∴ f = e = k. From equation (1), a + e + d + g = 2 (b+ f + c)

a + k + d + 3k = 2 (b + c) + 2k a + d = 2(8k – a) – 2k. 3a + d = 14k → (3)

From equation (2), we get, 4d + 11k = 5b + a → (4) Again number of students who opted for only Finance & HR, i.e., d was 50% of those who opted for only Finance i.e., a. ⇒ d = 50% a. Substituting in equation (3), we get d = 2k and a = 4k. Substituting in equation (4) we get b = 3k. Now (a + b + c + d + e + f + g) = 15k 15k = 270 ⇒ k = 18 ∴Exactly two = d + e + f = 4k = 4 (18) = 72 students. Choice (B)

Solutions for questions 16 and 17: It is given that books D and F was read by the same person, A and B was not read by the same person and F and C was not read by the same person. The different combinations in which the books were read are as follows:

V VΙ

A B A B C D C D E F E F H G G H

16. As Akira read books E and G, the books that Akira read

could be either A, C, E and G or B, C, E and G. In either case, we can conclude that Aroki did not read book C. Choice (D)

17. As books C and E, were not read by the same person,

as in cases Ι and ΙV, books G and H were read by the same person. Choice (C)

Solutions for questions 18 to 25: 18. W5 and W7 are allotted a shift, one earlier than W6 and

W3 and W9 are also allotted a shift earlier than W6. Again as W3 is allotted a shift lower than W2, if we allot the afternoon shift for W3 and W9; W5 and W7 being one shift earlier than W6, we will have four workers in the Afternoon shift if W6 is allotted the Evening shift. Thus the only shift that can be alloted to W6 is the Night shift. The following table gives the workers and the shift they were allotted to.

Page 14: Di Replica Last4years Sol

14

Morning W2

Afternoon W1, W3, W9

Evening W5, W7

Night W4, W6

Thus W8 can be allotted any shift other than the afternoon shift. Choice (B)

19. The following table lists down the matches and the

corresponding players who led the team as captain and vice captain.

Match Captain Vice Captain Match 1 B A/D Match 2 A C Match 3 B A/D Match 4 C A/B/D Match 5 D A/B/C

As D refused to lead the team as captain if A or B led the team as captain in the preceding match, we can conclude that D can be the captain of the team only in Match 5.

Again with D as Captain in Match 5, A must have captained the side in Match 2 for A cannot be the captain in Match 4.

Now with A as the captain in Match 2, C must have been the vice captain in that match.

Thus C was the vice captain in Match 2. Choice (C)

20. For B:

Person Appliances Day Water Purifier Monday Refrigerator Tuesday B

For A or C: AC must be bought before the water purifier.

Choice (B) 21. Number of matches played by Sachin is equal to that

played by Mongia. Number of matches played by Dravid is equal to that played by Hussey. Since Sachin has played more matches than Dravid, the average runs must be less than 45. Choice (A)

282=

Average (Sanjay) = .437

301=

If the average score after the exclusion lies between 40.28 and 43, then the average of Ramesh will decrease while that of Sanjay will increase. Since, 92 is the only value lying in that range, so their score in the invalid question is 42. Choice (A)

23. A wins ⇒ B wins B wins ⇒ C does not win. That implies both A and C do not win together. That means at most one of A or C wins. That further

implies that D must win. Choice (A) 24. Case (1) Day 1 / 2 / 3 Schumi Mclaren Sebastian Schumi Mclaren Sebastian Sebastian Schumi Mclaren Case (2) Day 1 / 2 / 3 Schumi Sebastian Mclaren Schumi Mclaren Sebastian Sebasian Schumi Mclaren

Since the sum of the ranks of Dimitry was 8 and he got

the same rank in Chemistry and Biology, his ranks in Chemistry and Biology was 1.

Therefore Dimitry’s rank in Mathematics was 2 which was the same as Emmanuel’s rank in Chemistry.

Emmanuel’s rank in Physics must have been 3. Ben got the same rank in Mathematics and Chemistry. Remaining ranks of Ben is be 4, 4 and 12. Therefore

Ben or Emmanuel did not get the 1st rank in Mathematics. Thus Adam’s rank in Mathematics was 1. Cathy got 3rd rank in Mathematics, therefore Ben got the 4th rank in Mathematics.

Proceeding like this we can conclude that Cathy got the 1st rank and Adam got the 2nd rank in Physics Choice (B)

34. It is given that at least 40 families own both a

Refrigerator as well as a Air conditioner. ∴ b + d is at least 40. We have to find the maximum value of a. a will be maximum when (b + d) is minimum. i.e., when (b + d) is 40. Now a+ c+ (b + d) + 24 + 20 + 26 = 120. a + c = 120 – 70 – (b + d) a + c = 10. ∴ The maximum value of a is 10, when c is 0. Thus at most 10 families owes a refrigerator and a LCD

TV but not an Air Conditioner Choice (A) 35. The lectures and the days on which they deliver the

lectures are tabulated in the following figure. Monday Tuesday Wednesday Thursday

Lecturers L1 L4 L2 L1 L3 L4 can deliver the lecture either on Tuesday or on

Wednesday. Now, if L4 delivers his lecture on Wednesday, then L3

cannot deliver his lecture on any of the given days. [Since L3 delivers a lecture only if L2 delivered a lecture

on the preceding day and L3 and L4 do not deliver lectures on consecutive days.]

Thus L4 delivers the lecture on Tuesday. Now, the only day on which L3 could have delivered the

lecture was Thursday Choice (D) 36. The different ways in which the committee can be

Duration 0 – 4 4 – 7 7 – 9 M1 P2 P1 P3 Duration 0 – 5 5 – 7 7 – 10 M2 P3 P2 P1 The total time taken is again 10 hours Choice (D) 38. Those playing exactly 3 games = g Those playing exactly 1 game = a + b + c Those playing exactly 2 games = d + e + f Those playing at least 2 games = d + e + f + g It is given that d + e + f + g = 18 → (1) and (a + b + c) + (d + e + f + g) = 30 → (2). Therefore a + b + c = 12. Now (a + b + c) = 3 (g). or, 3g = 12 or, g = 4. Therefore d + e + f = 18 – 4 = 14. Thus the number of members playing exactly two

games is 14 Choice (B) 39. We can list down the names of the countries and the

athletes belonging to them as follows.

Countries UK Germany France Switzerland Turkey 1. M6 M7 2. M8

It is given that M6 and M8 belonged to UK where as M7

belonged to Turkey. Now M5 and M9 were from different countries and M9

did not belong to France or Switzerland. So M9 belonged to either Germany or Turkey. Now M1 and M3 belonged to the same country and so

did M2 and M4. Let us consider two cases.

Case 1 M9 belonged to Germany.

UK Germany France Switzerland TurkeyM6 M9 M2 M1 M7. M8 M10 M4 M3 M5

Case 2 M9 belonged to Turkey.

UK Germany France Switzerland Turkey M6 M5 M2 M1 M7 M8 M10 M4 M3 M9

(As M5 did not belong to France or Switzerland) Thus M10 belonged to Germany Choice (C) 40. It is given that sum of the costs of the gifts bought by

the terms for the two contest can be selected as follows:

Debate: PVQ PVT PVS PVR PVT PVRPVR PVS PVU PVU PVR Elocution: PURPUR PURPUT PUS PUSPUT PUT PQS PQT PUQ

Debate: PVS PVT Elocution: PUQ PUQ

Option A is false as can be seen in the following cases: Debate: PVR PVS PVT Elocution: PUQ PUQPVQ

Option B is true. If V and U are in the same category it must be for Debate. We know that U being in debate implies R is not in elocution. Again since only one among S and T can be selected for a particular category, Q must be selected.

Option C is true as can be seen in the following cases: Debate: PVR PVS PVT Elocution: PUQ PUQPVQ

Thus only statement given in option A is false Choice (A)

NETWORKS 1. The cost incurred will be minimum when the distance

travelled is the minimum. The distance travelled is minimum when he takes a bus going via A E D F G H. The minimum cost incurred by him = 5 + 8 + 4 (10) = `53 Choice (3)

2. If the road connecting A to E is under repair, then to incur minimum cost, one must board a bus going via the route A D F G H. Since the total distance travelled along this route is the least. The cost incurred = 5 + 8 + 4 (12) = `61

1. Given that for every `2 increase in the selling price

per ball, the number of balls sold decreases by 20. ∴If the selling price of each ball is increased k times, selling price = `59 + 2k. ∴Profit per ball = (59 + 2k) – 50 = 9 + 2k. Number of balls sold = 700 – 20k. ∴Profit obtained = (9 + 2k) (700 +20k). Profit = 10 ((9 + 2k) (70 –2k))

= 10 (630 –18k + 140k –4k2) = 10 (630 – (4k2 –122k))

If 2k = 30, profit = 10 ((9 + 30) (70 – 30)) = 10 × 39 × 40 = `115600

If 2k = 31, profit = 10 ((9 + 31) (70 – 31)) = 10 × 40 × 39 = `115600

∴For maximum profit, Selling price = 59 + 2k = 59 + 30 = `89 or 59 + 31 = `90 When selling price is `89, balls sold = 700 – 300 = 400 When selling price is `90, balls sold = 700 – 320 = 380 Of the given choices, only (A) satisfies. Choice (1)

'x' and that in column 'b' and row 'b' be 'A'.

Given x = 31

(A + 26 + x)

⇒ 2x = A + 26 ⇒ x = )26A(21 +

As we know the grid contains only integers Therefore x should be an integer. Hence A should be even. From the choices only 16 is possible Choice (4)

12. Given the numbers in column 'a' are squares of the prime numbers, starting with the first odd prime number. Hence the numbers should be 32, 52, 72. 112 and 132. Thus, the required sum is 32 + 52 + 72 +112 + 132 = 373 Choice (4)

Solutions for questions 13 and 14:

(R, T), Q and U which can be arranged around the table (3 – 1)! × 2! ways [2! since RT can be arranged among the themselves] Now the remaining 2 persons can be placed in 2 of the 3 positions in 3C2 × 2! ways.

Therefore the total number of arrangements = (3 – 1)! (2!) (3C2) 2! = 24 ways. Choice (B)

7. Given B went to college on Thursday and did not teach

Physics. As A, B and C did not teach Physics, we can conclude that D taught Physics. As A and C went to college on consecutive days it can be either on Monday and Tuesday, or Tuesday and Wednesday. They cannot go to college on Tuesday and Wednesday as Physics is taught after Chemistry. Hence A and C go to college on Monday and Tuesday respectively. ∴Biology is taught on Monday.

Choice (1)

Solutions for questions 8 and 9:

Given Team I scored maximum number of points, 364 is at the 15th place and Team A got 361 points. Given the sum of the points scored by teams at (13 + 14 + 15) is 1046. 364 + 361 + x = 1046 ⇒ x = 321 Hence Team A is in the 14th place. As team C got 218 points and is in the 10th place and Team O got 251 points. Hence Team O should be placed between 11 -13. Given the ascending order of teams according to their points is O J F. Hence Team O is in the 11th place, team J is in the 12th place and Team F is in the 13th place with 321 points. Now we know the points of the teams in the 10th and the 11th place. Hence the points of the team in the 12th place is 284 points (from 10 + 11 + 12 = 753). As Team N and team B got 108 and 165 points respectively less than team F. Team N got 213 points and Team B got 156 points. The clue 7 + 8 + 9 = 590 implies that we can calculate the points of the third team in the above group. [We know N is one of the teams in the group] Hence 213 + 182 + x = 590. ⇒ x = 195 points. Hence Team N is in the 9th place. The clue Team E got 18 points less than Team N, implies that team E is in the 8th place. From the clue 4 + 5 + 6 = 412, we know B is one of teams in the group. Hence 116 + 156 + x = 412 ⇒ x = 140 Hence Team B is in the 6th place. The clue Team H got 4 points more than Team M, implies that Team K is in the 5th place. From the clue 1 + 2 + 3 = 302, we get 96 + x + 4 + x = 302 ⇒ x = 101 Hence Team M got 101 points and is in the 2nd place. Therefore Team H got 105 points and is in the 3rd place. The final arrangement is as follows.

1st 2nd 3rd 4th 5th 6th 7th 8th 9th 10th 11th 12th 13th 14th 15th Team L M H D K B G E N C O J F A I Points 96 101 105 116 140 156 182 195 213 2182 251 284 321 361 364

8. The required difference is 284 – 140 = 144 Choice (2)

9. The position of team E is 8th . Choice (2)

Solutions for questions 10 and 11:

Given P wears the Orange shirt and he orders Sprite and the person wearing the Green shirt orders Pepsi. From the clues, we know R wears the Red shirt, U wears the Blue shirt, T drinks Thumsup and Q drinks Coke. Hence R, Q, T and U neither wear Green nor order Pepsi. So the Green shirt is worn either by S or V. But from the clue, the person wearing Green shirt is the person who

orders Fanta and V orders the same dish. Hence we know that V does not wear the Green shirt. Therefore S wear the Green shirt and he orders Pepsi.

Let us tabulate the data.

V Violet shirt, Maaza is the correct combination. Choice (1) Solutions for questions 12 and 13: From the first and the last clue we get the following arrangement. From the third clue we know that the cricketer from India is at the extreme left end of the row and he plays for RCB. Also P is to the immediate right of him who plays for DC. Now from the 2nd clue we know that N is to the immediate left to the player who plays for KKR. From the above consideration we get the final arrangement as 12. M plays for RCB and comes from India. Choice (1) 13. The player from Australia plays for DC. Choice (4) Solution for questions 14 and 15: 14. Given X gave the presentation before T, R gave the

presentation before V but after U, also W gave the presentation after P and S but before U and X. So, Q, U, X, T, R and V (need not be in the same order) conducted the seminars after W. Hence W should be giving his presentation in group 1 with P and S. Choice (1)

15. From the choices we can say that X, U and Q can be

the first person to give the presentation in 2nd group but V cannot be the person. Choice (4)

16. Given R attends the Physics tuition, Q attends the

Maths tuition. Also P and U same tuition, T and V attend same tuition and S does not attend the same tuition as Q. Hence S should attend a tuition with at least 2 students in it. i.e. S should either attends Physics or Chemistry as there should be at least 2 students in each tuition. Q should attend a tuition to which 3 people go. Choice (4)

Solutions for questions 1 and 2: As policies mature in between 1997 and 2002 and a policy matures on Feb 29th, the policy should mature on 29th Feb 2000. Now the policy which matures on Jan 10th matured after Feb 29th. Hence the policy on Jan 10th can be in 1997 or in 2002. But from one of the clues the policy on May 21st is the last and the Sep 17th policy is immediately before the May 21st policy. Hence the policies on Sep 17th and Jan 10th should mature the same year. The policy on August 8th is before Feb 29th. Hence August 8th policy is for either 98 or 99. The final arrangement is as follows.

LA(Linear Arrangement) Solutions for questions 1 to 3: Given S is in 3rd place from the left end and the positions of F, Q, G are also given. As two of F, Q, G are from USA and there is atleast one person between any two friends from USA, we can say that F and G are from USA. Also the extreme ends are occupied by friends from USA. Now the friends from UK are separated by atleast four friends. So the other friend from UK can come either in the 2nd or the 4th position from the right. But from one of the clues P is from Australia and is in between Ι and J. Hence we can get it as. Now as R is adjacent to Ι and the friends at extreme ends are of different gender, we can get the final arrangement as follows. 1. F, G, Ι and J stay in the USA. Therefore four female

friends stay in the USA. Choice (4) 2. Three friends are in between the friends from the UK Choice (1) 3. T is the only male friend from USA. Choice (2) Solution for question 4 and 5: Given from (i) and (iv), the arrangement would be From the (iii) clue, U and V have 2 persons in between them. Hence we have only one possibility.[since there is only one person between Tarun and Qureshi] From the (ii) clue we get the final arrangement as 4. Raju is 3 places away to the left of Qureshi. Choice (4) 5. Pradip is to the immediate right of Shyam. Choice (3)

LA (Sequencing) Solutions for 1 to 3: From the clue, D got less than 3 other students hence D got the 4th rank. From the other clue E > C > A. Let us assume B got the highest marks. Then the order is B > E > C > A.

Now D got the 4th rank ⇒ D gets less than C. But the condition that one pair should have same marks is not satisfied. Hence E should get the highest marks. So E > C > A Now D cannot have more marks than C as D should have marks less than 3 students, hence C > D. As the first and the last ranked students do not have same marks as any other student, B should get the same marks as 'C'. Hence all the conditions are satisfied and the final arrangement is E > C = B> D > A. 1. E got the highest marks. Choice (4) 2. B and C got the same marks. Choice (2) 3. The descending order is ECBDA. Choice (1) Solutions for questions 4 and 5: Given at least 2 movies were released before R and there is one movie released between S and T. Hence R cannot be released on the 3rd or the 4th week of the month. It can only be released on the last week. Therefore Q is released on the 4th week. As S and T have one movie released between them, P is released on the 2nd week. Hence the final order would be as S/T, P, T/S, Q, R. 4. R is released last. Choice (3) 5. Only one movie is released before P. Choice (1)
