What is the least value of x so that the number 8x5215 becomes divisible by 9?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 6.
Given that
The number 8x5215 becomes divisible by 9
Divisibility rule of 9 : If the sum of digits of a number is divisible by 9 than that number also divisible by 9
The sum of the digits of the number = 8 + x + 5 + 2 + 1 + 5 = 21 + x
Hence, For the completely divisible by 9 the value of x should be 6
