Problem Solving (PS) | Re: In the correctly worked addition problem shown, P, Q, R, and S are dig

HelloVishlesh ,


I understand your doubt and I appreciate the fact that you thought about it and brought it forward.

There is actually more than just this one question that I need to explain here. The GMAC rolled out two versions of this question – one is old (the one you posted on) and the other is new (from OG ‘21 onwards).

1. Old Question - on GMATClub
2. New Question – OG ‘21 onwards

Let’s begin with your question on the older version.

Old Question - onGMATClub

In this version, choices D and E have negative integers {-1 and -2}. These choices were especially given to induce the doubt that you also have in mind presently - “if S can be negative, R and other digits can probably be negative as well.”

But, as I said, it is just a means to create confusion and trap students
