ques. must be answered on special machine gradable Objective Response Sheet (ORB) by darkening the improper bubble (marked A, B, C, D) using HB pencil against the ques. number on the left hand side of the ORS. every ques. has only 1 accurate ans. In case you wish to change an answer, erase the old ans completely using a good soft eraser.
There will be NEGATIVE marking. For every wrong ans 0.25 mark from Q. 1-30 and 0.5 mark from Q. 31-90 will be deducted. More than 1 ans marked against a ques. will be deemed as an incorrect response and will be negatively marked.

Q. one - 30 CARRY 1 MARK every



1. Consider the subsequent C function.

float f,(float x, int y) {

float p, s; int i;

for (s=1, p=1, i=1; i < y; i ++) {

p*= x/i;

s+=p;

}

return s;

}



For large values of y, the return value of the function f best approximates
X Y
e x
ln (1 + x)
X X



2. presume the subsequent C variable declaration

int *A [10], B [10][10];

Of the subsequent expressions
A[2]
A [2] [3]
B [1]
B [2] [3]

which will not provide compile-time errors if used as left hand sides of assignment statements in a C program ?
I, II, and IV only
II, III, and IV only
II and IV only
IV only



3. Let P(E) denote the probability of the event E. provided P(A)= 1, P(B) = 1/2, the values of P(A \ B) and P(B / A) respectively are
¼, ½
½, ¼
½, one
1, ½


Let A be a sequence of eight distinct integers sorted in ascending order. How many distinct pairs of sequences, Band C are there such that (i) every is sorted in ascending order, (ii) B has five and C has eight elements, and (iii) the outcome of merging B and C provide A ? .
