Question

Find the smallest value of x such that the number 25x397 is divisible by 9​

Answer 1

Divisibility of 9: The sum of all number is divisible by 9.

25x397

=2+5+3+9+7=26

9×2=18 is smaller than 26.

9×3=27 is greater than 26.

So, we take 9×3=27

27-26=1

So, the value of x is 1.

Hope it is helpful.
