This time CSIR does not allow candidates to carry questions with them. We have collected maximum questions from our candidates (memory based).

1. What is the minimum number of moves required to transform figure 1 to figure 2? A move is defined as removing a coin and placing it such that it touches two other coins in its new position.

Ans: 3
Expln:- 2. The set of numbers (5, 6, 7, m, 6, 7, 8, n) has an arithmetic mean of 6 and mode (most frequently occurring number) of 7. Then m x n =
1. 18
2. 35
3. 28
4. 14

Ans:-4,

Expl:- (5, 6, 7, m, 6, 7, 8, n)
Arithmetic mean = 5 + 6 + 7 + m + 6 + 7 + 8 + n       /     8
6 = 5 + 6 + 7 + m + 6 + 7 + 8 + n      /     8
6 x 8 = 39 + m + n
48 – 39 = m + n
m + n = 9
Mode = 7
ie, 7 is the most frequent number. So either m or n is 7. If m = 7, n = 9 – 7 = 2
ie, m = 7, n = 2
then m x n = 7 x 2 = 14

3.  It takes 5 days for a steamboat to travel from A to B along a river. It takes 7 days to return from B to A. How many days will it take for a raft to drift from A to B ( all speeds stay constant)?
1.   13
2.   35
3.   6
4.   12
Ans:- 2
