A and B are positive integers. If A + B + AB = 65, then what is the difference between A and B (A, B ≤ 15)?
A. 3
B. 4
C. 5
D. 6
Answer: Option C
Solution (By Examveda Team)
A + B + AB = 65(A, B ≤ 15)
Assume value of A & B
A = 10
B = 5
10 + 5 + 10 × 5 = 65
65 = 65 value satisfied
Difference between (A - B) = 10 - 5 = 5
