11. Gavaskar's average in his first 50 innings was 50. After the 51st innings, his average was 51. How many runs did he score in his 51st innings.
(supposing that he lost his wicket in his 51st innings)?
A.106
B.103
C.101
D.none of these
Answer: C
Explanation:
Total score after 50 innings = 50*50 = 2500. Total score after 51 innings = 51*51 = 2601. So, runs made
in the 51st innings = 2601-2500 = 101.
If he had not lost his wicket in his 51st innings, he would have scored an unbeaten 50 in his 51st innings.

13. If s(a) denotes square root of a, find the value of s(12+s(12+s(12+ ...... upto infinity
A.8
B.5
C.4
D.none of these
Answer: C
Explanation:
Let x = s(12+s(12+s(12+..... We can write x = s(12+x). i.e., x^2 = 12 + x. Solving this quadratic equation, we get x = -3 or x=4.
Sum cannot be -ve and hence sum = 4.
14. If point P is on line segment AB, then which of the following is always true?

C. PB > AP
D. AB > AP
E. AB > AP + PB
A.A
B.E
C.C
D.D
Answer: D
Explanation:
p ------------------------ A B Since p is a point on the line segment AB, AB > AP
15. If a = 2, b = 3, c = 6
Find the value of c/(a+b)-(a+b)/c

16. main( )
{
int x,y, z;
x=2;
y=5;
z= x+++y;
printf("%d %d %d", x, y z);
}
A.3,5,7
B.2,6,8
C.3,5,8
D.2,6,7
Answer: A
Explanation:
This statement can be broken to z = x + y; (i.e z = 7 ) x = x + 1; (i.e x = 3 ) Hence Correct Answer is : 3,5,7
