Feed them ORANGE
I have a truck full of \(200\) oranges. I want you to divide them among 13 girls and 5 boys, so that each girl gets \(m\) orange(/s) and each boy gets \(n\) orange(/s).
Consider, \(a=m+n\) ;
What is the sum of all possible values of \(a\) ?
Details and assumptions
\(m\) and \(n\) must be non-zero positive integers.
All 200 oranges must be distributed.
