Dear SajjadAhmad,

I'm happy to respond. :-) This is a great question!

Statement #1: p(r + s) = 5 and q(r + s) = 3

Simply add those two equations

p(r + s) + q(r + s) = 5 + 3
(p + q) (r + s) = 8

This statement leads to a direct unambiguous numerical answer to the prompt question. This statement, alone and by itself, is sufficient.

Statement #2: (p + q) = (r + s)

This tells us that
\((p + q) \times (r + s) = (p + q) \times (p + q) = (p + q)^2\)

That's interesting, but it does not allow us to arrive at a specific numerical value. This statement, alone and by itself, is insufficient.

OA = (A). A great question!

Mike :-)
