If the remainder when $x$ is divided by 5 equals to the remainder when x is divided by 4 then x could be any of the following a)20 , b)21 , c)22 , d)23 e)24 (Ans=(e)24)

Now I could only tell till $x-5q=x-4p$.

Using equations how can I predict the values of x ?

    Any of (a), (b), (c), and (d) work: leave remainders of 0, 1, 2, and 3 respectively. 24 is **not** a valid answer, because the remainder when divided by 4 is $0$, but the remainder when divided by 5 is $4$, and $0\neq 4$.2012-07-17
