Question: A and B are two positive integers such that A × B = 96. Which of the following cannot be the value of A + B? Solution:Factor pairs of 96:(1, 96) → A + B = 97(2, 48) → A + B = 50(3, 32) → A + B = 35(4, 24) → A + B = 28(6, 16) → A + B = 22(8, 12) → A + B = 20So, possible values of A + B are:97, 50, 35, 28, 22, 20Among options, 49 is not possible.
