(c)8 and 0
(d)None of these
Answer
Answer (as printed): C
Explanation
Since 774958A96B is divisible by 8, so the number 96B must be divisible by 8. So, B = 0, as 960 is divisible by 8. Now, 774958A960 is divisible by 9. So, (55 + A) must be divisible by 9. This happens when A = 8. Hence, A = 8 and B = 0.
