If a number 774958A96B is to be divisible by 8 and 9, the respective values of A and B will be
Show Hint
- 7 and 8
- 8 and 0
- 5 and 8
- None of these
The Correct Option is B
Solution and Explanation
Divisibility by 9 → sum of digits divisible by 9. With B=0, sum = $7+7+4+9+5+8+A+9+6+0 = 55 + A$. For 9-divisibility, $55 + A$ must be multiple of 9 → A=8.
