If a number 774958A96B is divisible by 8 and 9, the respective values of A and B will be :
Options:
A . 5 and 8
B . 7 and 8
C . 8 and 0
D . None of these
Answer: Option C 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
