If the seven digit number 5x634y2 is divisible by 88 such that x≠y, then what is the value of (2y - 3x)?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 6.
Last 3 digits = 4y2, divisible by 8
y = 3, then 432 ÷ 8 = 54
Now full number: 5x63432
Check divisibility by 11: 5 − x + 6 − 3 + 4 − 3 + 2 = 11−x
11−x=11
⇒x = 0, and x ≠ y
2y − 3x = 2(3) − 3(0) = 6
