Solution

The correct option is D None of these
The number 774958A96B is divisible by 8 if 96B is divisible by 8. And 96B is divisible by 8 if B is either 0 or 8. Now to make the same number divisible by 9 sum of all the digits should be divisible by 9. Hence (55+A+B) is divisible by 9 if (A+B) is either 8 or 17 either A = 0, 9 and B = 8 or A = 8 and B = 0.
