If 572X41 is divisible by 9, then what is the value of X?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 8.
For divisibility by 9, the sum of digits must be divisible by 9
Sum of known digits: 5 + 7 + 2 + 4 + 1 = 19
19 + X should be divisible by 9
19 + X = 27 (next multiple of 9)
X = 27 - 19 = 8
