If B > A, then which expression will have the highest value (given that A and B are positive integers)

A. A - B

B. AB

C. A + B

D. Can't say

Answer: Option D

Solution(By Examveda Team)

B > A ⇒ A < B ⇒ (A - B) < 0
Since A and B are both positive integers, we have (A + B) > 0 and AB > 0
If (A = 1 and B = 2), we have AB < (A + B)
If (A = 2 and B = 3), we have (A + B) < AB
Thus, we cannot say which one of A + B and AB has the highest value.
