Question

If 1A2B5 is exactly divisible by 9️9 then what is the least value of A+B?

Answer 1

10 is the answer
because the sum of characters must be divisible by 9
here sum is 8+a+b
hence a+b must be 10

Answer 2

10 bcz the addition of the no is divisible by 3 then it is also divided by 9 first to find a we added the least of the numbers like 1+2+5=8 so we have to find two numbers whose addition is divisible by 9 so we imagined a as 3 and b as 7 so 1+3+2+7+5=18 and 18 is divisible by 9 the number is 13275
