Answer»

3



The least number to be ADDED to the numbers to MAKE them divisible by 9 is equal to the difference of the least MULTIPLE of 9 GREATER than the sum of the digits and sum of the digits.

Sum of digits = 15.

Nearest multiple of 9 greater than sum of digits = 18.

Hence 3 has to be added.
