PREVIOUS SOLVED QUESTIONS – 2014 December CSIR – NET EXAM

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

1. Three volumes of a Hindi book, identical in shape and size, are next to each other in a shelf, all upright, so that their spines are visible, left to right: I, II and III. A worm starts eating from the outside front cover of volume I, and eats its way horizontally to the outside back cover of volume III. What is the distance travelled by the worm, if each volume is 6 cm thick ?
1.   6 cm   2.   12 cm   3.   18 cm   4.   a little more than 18 cm

Ans: 4
Expln:- Explanation : There is some distance between each books. So, even though the thickness of the books is 3 x 6 = 18, the worm travels little more than 18 cm.

2.The sum of first n natural numbers with one of them missed is 42. What is the number that was missed ?
1.   1   2.   2   3.   3   4.   4

Ans:- 3
Expln:- 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 45.
Then 45 – 42 = 3

3. Which of the following figures best shows that y is inversely proportional to x ?
2014_dec_a_1

Ans:- 2

Expln:- In the figure No. 2, as x value increases, y starts decreases. Hence y is exactly inversely proportional to X.

4. If N, E and T are distinct positive integers such that N x E x T = 2013, then which of the following is the maximum possible sum of N, E and T ?
1.   39   2.   2015   3.   675   4.   671Ans:- 3

Expln:- Maximum possible sum of N, E and T will be 1 + 3 + 671 = 675.
