If ` 3x2` is a multiple of 11, where `x` is a digit, what is the value of `"x"` ?

Explanation

A number is divisible by `11` if and only if the difference between the sum of odd and even place digits is a multiple of `11`.
i.e., Sum of even placed digits – Sum of odd placed digits `=0,11,22…`
`x–(3+2)=0,11,22…`
`x–5` is a multiple of `11`
`x–5=0`
Hence, `x=5.`
