Choose the correct choice from the following options
A) 12
B) 17
C) 18
D) 77
E) 26
Explanation:   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.   Answer: 18
