If 7-digit number 485A64B is divisible by 8 and 9, then find the greatest value of A + B.

✅ Correct Option: 3

Divisible by 8: last 3 digits '64B' divisible by 8, so B=0 or 8. Divisible by 9: sum $4+8+5+A+6+4+B=27+A+B$ divisible by 9, so $A+B$ is 0, 9, or 18. With B=8: $A+B=9$ means A=1, or $A+B=18$ means A=10 (invalid). With B=0: $A+B=9$ means A=9. Maximum $A+B=9$ .
