Question

If 1A2B5 is exactly divisible by 9, then the least value is(A+B)​

Answer 1

Answer:Any number to be divisible by 9, the sum of its digits should also be divisible by 9.

1+A+2+B+5 = 8+A+B

8+A+B = 9

A+B = 9–8 = 1

So, 1 is the least value of A+B. (Where the two digits are 0 & 1).

The original number could be 10215 / 11205 only when A+B is the least value, as shown above.
