Hi all I think OG has lost it with this question. I don't agree that their answer is right. I think its not possible to find the answer with the options.. We have had a big fight over this at my home.. One thinks the answer is right, I think its wrong:

So here goes the question..

Q) In a nationwide poll, N people were interviewed. If 1/4 of them answered yes to question 1, and of those, 1/3 answered yes to question 2, which of the following expressions represents the number of people interviewed who did not answer yes to both questions?

a) N/7

b) 6N/7

c) 5n/12

d) 7N/12

e) 11N/12

I think it is none of these.. Please explain as to why it is 11N/12

Here is my table from the above data..:

-----------Q1yes------Q1no-------Total

Q2yes------N/12

Q2no-------N/6

Total-------N/4--------3N/4----------N

Please explain.. before we have a third world war at home!

I tyhink it isall interpretation of this question.. confusing! I am going to be online for the next 30 mins.. want to solve this before the war goes too far

Willget....

I took quite some time understanding this problem...and when i did..i cursed myself...for wasting so much time on this silly problem

it goes like this....

it says...1/3 of the ppl for the question1 right...ok fine....

but then it says...1/4 of that 1/3 also got the 2nd question rite...

1/4*1/3 = 1/12

so this 1/12 includes total of ppl who got both question 1 and 2 rite...

so no of ppl who got both wrong = 1-1/12 = 11/12

thats it .....

u can go and compromise with that person...he/she is rite !!
