If the number 8764x5 is divisible by 9, then find the least possible value of x where x is a two–digit number
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 15
If the number 8764x5 is divisible by 9
then the sum of the digits of this number is also divisible by 9
8 + 7 + 6 + 4 + x + 5 = 30 + x
the least value of x = 15 then it is divisible by 9 completely.
