Question

Given that the numbers 60AB57377 is divisible by 99, where A and B are digits. Find the possible value of A and B.

Answer 1

This is pretty simple.
99 can be written as 9*11.
So we know the following number must be divisible by 9 and 11
Add all the digits to check divisibility by 9.
We'll have 35+A+B. A+B can be 1 or 10.
And 21+A-(14+B)= 11.
We have A-B=4.
Solve the 2 equations, we have A=7 and B=3.
