Data Sufficiency (DS) | Re: If m/n = 1/2, what is the value of m + n ?

Statement 1: m=2/n.
On putting this in original equation we get two values of n.. +2 and -2 so we will have two different values of m also.

Insufficient.

Statement 2: simply tells n is positive. Not sufficient.

Statement 1+2:
N=2 and m=1.

Sufficient. C is the answer
