A and B are in a line to purchase tickets. How many people are in the line?

(1) There are 15 people behind A and 15 people in front of B.
(2) There are 5 people between A and B.

Explanation:

S1: As no. Of people between A& B and relative sequence of A& B not given thus not possible to tell exact number.

Hence S1 insufficient.

S2: although no. Of people between A& B given but people behind and ahead information is not provided.

Hence S2 insufficient.

Combining S1 & S2

As standing sequence of A& B is not given i.e whether A is ahead of B or vice versa thus it is impossible to tell total no. Of people in line.

Hence E is the correct answer.

Statement 1 ) There are 15 people behind A and 15 people in front of B. statement 1.png statement 2 ) There are 5 people between A and B. statement 2.png 1+2 Gmat club.png Hence answer is E. Edit: Error corrected thanks to IanStewart for pointing it out

I'm not sure why you've declared one case impossible when you used both Statements. The answer is E because we don't know if A is in front of B in line, or if A is behind B in line. So you could have this line, where each dot is a person:

• • • • • • • • • A • • • • • B • • • • • • • • •

and then there are five people between A and B, 15 behind A (including B), and 15 ahead of B (including A), or you could have this line

• • • • • • • • • • • • • • • B • • • • • A • • • • • • • • • • • • • • •

and again there are five people between A and B, 15 behind A, and 15 ahead of B. But this line is much longer than the first one, so the answer is E.

Right. Thank you Sir, Silly of me to goof up. Don't know why I thought there cannot be 15 people behind A with includes B.
