If ` 24 y5` is a multiple of 3, where y is a digit , what might be the value of `y` ?

Explanation

Since the number` 24y5` is a multiple of `3`.
So, the sum of its digits` 2+4+y+5=11+y` is a multiple of `3`.
`(11+y)` is either 0 or 3 .
Since` y` is a digit, so `(11+y)` must be equal to `3`.
i.e., `11+y=3`
`=y=3−11=-8`
