If B > A, then which expression will have the highest value (given that A and B are positive integers)
Options:
A . A - B
B . AB
C . A + B
D . Can't say
Answer: Option D 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.
