I am not sure how the answer is A..
This is coming from the big book.
Can anyone explain?

any takers?

On solving, you will realize that 2n+r = s + 4/3*t

Comparing s + 4/3*t with 2s + t. we get 1/3t compared with s. Seeing that they can take just about any values, I feel that the answer is D.

You sure that the 8 under the 's' is an 8? And not a 3?

After much tomfoolery... the ans is straightforward... to elaborate... two possible solutions are:
(2,4,4,3),(8,1,1,12)... you can see that for the first A<B... for the second A>B... D

Let's make all the fractions equal to 1.

Then n=4
r=8
s=8
t=6

2n+r=16
2s+t=16+6=22

Does the q say that the integers have to be different? Here is at least one case where B is greater, so the answer can't be A.

yes... nowhere does it say that they cant be the same...
