When 335 is added to 5A7, the result is 8B2, 8B2 is divisible by 3, What is the largest possible value of A?
[A]1
[B]4
[C]2
[D]8

4
5 A 7 + 3 3 5 = 8 B 2
=> A – 1, 2, 3, 4, 5 & B – 5, 6, 7, 8, 9
and 8B2 is exactly divisible by 3
∴ 8 + B + 2 = Multiple of 3
∴ B = 5 or 8 and A = 1 or 4
Hence option [B] is the right answer.
