ummm i will solve the PS this following way
N/4 -> yes (1) => 3N/4 No (1)
n/4*1/3=N/12 yes (2) so N/4-N/12=1N/6 no (2)
the number both answer no is 3N/4-1N/6=7N/12

Saurabh, I would answer it this way...

# of people who answered NO to question 1:
(3/4)N

# of people who answered YES to question 1 AND NO to question 2:
(1/4)N * (1 - 1/3) = (1/4)N * (2/3) = (2/12)N

Summing both the above leads to:
(3/4)N + (2/12)N = (9/12)N + (2/12)N = (11/12)N

So the number of people interviewed who did not answer to BOTH questions is (11/12)N, which is (E).

Trust this explains your question.

To find the No. of people did not answer yes to both question, just find the no. of them that did say yes to both question, then subtract the total no. of people to the no. of who said yes to both.

No. of people said yes to 1st question: 1/4N
Of those said yes to 1st, 1/3 said yes to the second, hence no. of people said yes to both : 1/4N* 1/3 = 1/12*N

Thus no. of people did not say yes to both questions: 1N- 1/12*N = 11/12*N
Pick E.
