# Replace $ ^{\star} $ by a digit in $388^{\star} 62$ so that the number is divisible by 9.

**Given :**

The given number is $388^{\star} 62$.

**To do :**

We have to replace $ ^{\star} $ by a digit in $388^{\star} 62$ so that the number is divisible by 9.

**Solution :**

To be divisible by 9, the number obtained by adding the digits of the number should be divisible by both 3 and 9.

Sum of digits of the given number $388^{\star} 62 = 3 + 8 + 8 + ^{\star} + 6 + 2 = 27+^{\star}$

This is divisible by 9 if $^{\star}$ is either 0 or 9

that is the number becomes either 388062 or 388962

**Therefore, the $^{\star}$ can be replaced by 0 or 9; **
