GMAT Problem Solving (PS) | Re: If the remainder is 1 when m is divided by 2 and the remainder is 3

m is odd as it not divisible by
n is odd as it is not divisible by 4.
If n is even it would have given remainder of 2 , For example 10/4 remainder is 2
when it is odd 7/4 remainder is 3.
m+n is even
