When 335 is added to 5A7, the result is 8B2, 8B2 is divisible by 3, What is the largest possible value of A?
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.
