3.

Robert is travelling on his cycle and has calculated to reach point A at 2 P.M. if he travels at 10 kmph,

he will reach there at 12 noon if he travels at 15 kmph. At what speed must he travel to reach A at 1

P.M.?

A. 8 kmph

B. 11 kmph

C. 14 kmph

D. 12 kmph

ANS: D

Let the distance travelled by x km.

Then, x - x = 2

10 15

3x - 2x = 60

x = 60 km.

Time taken to travel 60 km at 10 km/hr = 60 hrs = 6 hrs.

10

So, Robert started 6 hours before 2 P.M. i.e., at 8 A.M.Required speed = 60 kmph. = 12 kmph.

140

(5 women + 10 children)'s day's work = 5 + 10 = 1

9 leaves no remainder, is:

A. 1677

B. 3363

C. 2523

D. 1683

ANS: D

L.C.M. of 5, 6, 7, 8 = 840.

Required number is of the form 840k + 3

Least value of k for which (840k + 3) is divisible by 9 is k = 2.

Required number = (840 x 2 + 3) = 1683.

B. 49

C. 12

D. 9

ANS: D


21/29

Let the required number of revolutions made by larger wheel be x.

Then, More cogs, Less revolutions (Indirect Proportion)

14 : 6 :: 21 : x 14 x x = 6 x 21

x = 6 x 21

x = 9.

7. Five farmers have 7, 9, 11, 13 & 14 apple trees, respectively in their orchards. Last year, each of

them discovered that every tree in their own orchard bore exactly the same number of apples.

Further, if the third farmer gives one apple to the first, and the fifth gives three to each of the

second and the fourth, they would all have exactly the same number of apples. What were the yields

per tree in the orchards of the third and fourth farmers?

A. 9 & 11 apples per tree

B. 11 & 9 apples per tree

C. 11 & 11 apples per tree

D. 9 & 9 apples per tree

ANS: B

Let a, b, c, d & e be the total number of apples bored per year in A, B, C, D & E ‘s orchard. Given that

a + 1 = b + 3 = c – 1 = d + 3 = e – 6

But the question is to find the number of apples bored per tree in C and D ‘s orchard. If is enough to

consider c – 1 = d + 3.

Since the number of trees in C’s orchard is 11 and that of D’s orchard is 13. Let x and y be the

number of apples bored per tree in C & d ‘s orchard respectively.

Therefore 11 x – 1 = 13 y + 3

By trial and error method, we get the value for x and y as 11 and 9

8. What is the sum of all numbers between 100 and 1000 which are divisible by 14 ?

A. 34398

B. 35280

C. 36400

D. 35392

ANS: D

The number closest to 100 which is greater than 100 and divisible by 14 is 112, which is the first

term of the series which has to be summed.


22/29

The number closest to 1000 which is less than 1000 and divisible by 14 is 994, which is the last term

of the series.

112 + 126 + .... + 994 = 14(8+9+ ... + 71) = 35392

9. A man invested Rs. 14,400 in Rs.100 shares of a company at 20% premium. If the company

declares 5% dividend at the end of the year , then how much does he get?

A. Rs. 500

B. Rs. 650

C. Rs. 600

D. Rs. 720

ANS: C

Number of shares = (14400 / 120)

=120.

Face value =Rs.(100 ×120)

=Rs. 12000.

Annual Income = Rs.(5/100 ×12000)

=Rs. 600.

10. Rajan got married 8 years ago. His present age is 6 / 5 times his age at the time of his marriage.

Rajan's sister was 10 years younger to him at the time of his marriage. The age of Rajan's sister is

A. 32 years

B. 38 years

C. 36 years

D. 40 years

ANS: B

Let Rajan's present age be x years. Then, his age at the time of marriage =(x-8) years.Therefore x= 6/5(x-6)

5x = 6x-48

x=48.

Rajan's sister's age at the time of his marriage=(x-8)-10 =(x-18)=30

Rajan's sister's present age =(30+8)

= 38 years.

11. A tap can fill a tank in 6 hours. After half the tank is filled, three more similar taps are opened.

What is the total time taken to fill the tank completely ?

A. 3 hrs 15 min

B. 4 hrs

C. 3 hrs 45 min


23/29

D. 4 hrs 15 min

ANS:C

Time taken by one tap to fill half the tank = 3hrs.

Part filled by the four taps in 1 hour = (4×1/6)

= 2/3.

Remaining part = (1 - 1/2)

= 1/2.Therefore, ‹=› 2/3 : 1/2 :: 1 : x

‹=› (1/2×1×3/2)

‹=› 3/ 4 hrs i.e 45 mins.

So, total time taken = 3 hrs 45 min.

12. A man earns on the first day and spends Rs. 15 on the next day. He again earns Rs. 20 on the

third day and spends Rs. 15 on the fourth day. If he continues to save like this, how soon will he have

Rs. 60 in hand?

A. on 27th day

B. on 17th day

C. on 30th day

D. on 40th day

ANS: B

Money earned in 2 days = Rs.(20 - 15)

‹=›Rs. 15.

Money earned in 16 days = Rs.(5/2 x 16)

‹=›Rs. 40.

On 17th day, money in hand = Rs.(40 + 20 )

= Rs. 60.

13. A boat takes 19 hours for travelling downstream from point A to point B and coming back to a

point C midway between A and B. If the velocity of the stream is 4 kmph and the speed of the boat in

still water is 14 kmph, what is the distance between A and B ?

A. 160 km

B. 220 km

C. 200 km

D. 180 km

ANS: D

Speed Downstream = (14 + 4) km/hr

= 18 km/hr.

Speed upstream =(14 - 4) km/hr= 10 km/hr..

Let the distance b/w A and B

be xkm.Then =(x/18+ x/2 / 10)

= 19

= 19x / 180 = 19


24/29

x= 180.

14. A milk vendor has 2 cans of milk.The first contains 25% water and the rest milk.The second

contains 50% water. How much milk should he mix from each of the containers so as to get 12 litres

of milk such that the ratio of water to milk is 3 : 5 ?

A. 4 lit, 8 lit

B. 6 lit, 6 lit

C. 5 lit, 7 lit

D. 7 lit, 4 lit

ANS:B

Let the cost of 1 litre milk be Re. 1

Milk in 1 litre mix. in 1st can = 3/4 litre, C.P. of 1 litre mix. in 1st can Re. 3/4

Milk in 1 litre mix. in 2nd can = 1/2 litre, C.P. of 1 litre mix. in 2nd can Re. 1/2

Milk in 1 litre of final mix. = 5/8 litre, mean price = Re. 5/8.

By the rule of alligation, we have:

Cost of 1 kg mixture of 1st kind Cost of 1 kg mixture of 2nd kind

Ratio of two mixtures = 1/8 : 1/8 = 1:1.

So, quantity of mixture taken from each can = (1/2 X 12) = 6 litres

15. In how many different ways can the letters of the word 'AUCTION' be arranged in such a way

that the vowels always come together?

A. 30

B. 48

C. 144

D. 576

ANS: D

The word Auction has 7 different letters.

When, the vowels AUIO are always together, they can be supposed to form one letter.Then, we have to arrange the letters CTN (AUIO).

Now, 4 letters can be arranged in 4! = 24 ways.

The vowels (AUIO) can be arranged in 4!= 24 ways.

Required number of ways = (24 x 24)

= 576.

27. To print out a and b given below, which of the following printf() statement will you use?

#include

double b=3.14;

A. printf("%Lf %f", a, b);

28.

29. What will be the output of the program ?

{

char p[] = "%d\n";

p[1] = 'c';

printf(p, 65);

return 0;

}

A. a

B. A

C. c

D. 65

ANS: B

Step 1: char p[] = "%d\n"; The variable p is declared as an array of characters and initialized with

string "%d".

Step 2: p[1] = 'c'; Here, we overwrite the second element of array p by 'c'. So array p becomes "%c".

Step 3: printf(p, 65); becomes printf("%c", 65);

Therefore it prints the ASCII value of 65. The output is 'A'.

30.

What will be the output of the program ?

#include


29/29

int main()

{

return 0;

}

A. Good Morning

C. Morning

D. M

ANS: C

printf(5+"Good Morning\n"); It skips the 5 characters and prints the given string.

Hence the output is "Morning"
