11) If G(0) = -1 G(1)= 1 and G(N)=G(N-1) - G(N-2) then what is the value of G(6)?ans: -1bcoz g(2)=g(1)-g(0)=1+1=2g(3)=1g(4)=-1g(5)=-2g(6)=-1

12) If A can copy 50 pages in 10 hours and A and B together can copy 70 pages in 10 hours, how much time does B takes to copy 26 pages?Sol) A can copy 50 pages in 10 hrs.A can copy 5 pages in 1hr.(50/10)now A & B can copy 70 pages in 10hrs.thus, B can copy 90 pages in 10 hrs.[eqn. is (50+x)/2=70, where x--> no. of pages B can copy in 10 hrs.]so, B can copy 9 pages in 1hr.therefore, to copy 26 pages B will need almost 3hrs.since in 3hrs B can copy 27 pages.

13) what's the answer for that :A, B and C are 8 bit no's. They are as follows:A -> 1 1 0 0 0 1 0 1B -> 0 0 1 1 0 0 1 1C -> 0 0 1 1 1 0 1 0 ( - =minus, u=union)Find ((A - C) u B) =?To find A-C, We will find 2's compliment of C and them add it with A,That will give us (A-C)2's compliment of C=1's compliment of C+1=11000101+1=11000110A-C=11000101+11000110=10001001Now (A-C) U B is .OR. logic operation on (A-C) and B10001001 .OR . 00110011The answer is = 10111011,Whose decimal equivalent is 187.

14) One circular array is given(means memory allocation tales place in circular fashion) diamension(9X7) and sarting add. is 3000, What is the address of (2,3)........Sol) it's a 9x7 int array so it reqiure a 126 bytes for storing.b'ze integer value need 2 byes of memory allocation. and starting add is 3000so starting add of 2x3 will be 3012.

15) In a two-dimensional array, X (9, 7), with each element occupying 4 bytes of memory, with the address of the first element X (1, 1) is 3000, find the address of X (8, 5).Sol) initial x (1,1) = 3000 u hav to find from x(8,1)so u have x(1,1),x(1,2) ... x(7,7) = so u have totally 7 * 7 = 49 elementsu need to find for x(8,5) ? here we have 5 elements each element have 4 bytes : (49 + 5 -1) * 4 = 212 -----( -1 is to deduct the 1 element ) 3000 + 212 = 3212

16) Which of the following is power of 3 a) 2345 b) 9875 c) 6504 d) 9833

17) The size of a program is N. And the memory occupied by the program is given by M = square root of 100N. If the size of the program is increased by 1% then how much memory now occupied ?Sol) M=sqrt(100N)N is increased by 1%therefore new value of N=N + (N/100)=101N/100M=sqrt(100 * (101N/100) )Hence, we get M=sqrt(101 *  N)

1) Horse started to chase dog as it relieved stable two hours ago. And horse started to ran with average speed 22km/hour, horse crossed 10 mts road and two small pounds with depth 3m, and it crossed two small street with 200 mts length. After travelling 6 hrs, 2 hours after sunset it got dog. Compute the speed of dog?Ans: As we have speed and travel time of horse, we can get distance travelled by it.  Hence d = 22*6 = 132km,Exactly this 132km was travelled by dog in 8 hours (as it started two hours earlier).Hence speed of dog = 132/8 = 16.5km/hrAns: 16.5km/hr.
