List few members for \(m + n\). for eg. \({8, 20, 32}\)

List few members for the set \(m-n\). for eg. \({6,18,30}\)

now make a equation by chosing any pair of values

\(m+n = 8...........i\)

\(m-n = 6...........ii\)

subtracting eqn \(ii\) from \(i\) we get,

\(2n =2 or n =1\)

Putting \(n =1\) in eqn \(i\) we get \(m + 1 = 8 or m = 7\)

therefore\(m*n = 7\)

\(\frac{7}{6}\) gives a remainder of \(1\)

option A
