If m>0 & n>0, then (m+x)/(n+x) > m/n
1) n>m
2) x >0
As per OG answer it is mentioned that both statements are reqd to answer. The answer choice is C. But why the statement 1 alone cannot be sufficient to answer this qn
(m+x) / (n+x) > m/n
Multiply both sides by n+x ,then by n, then the statement becomes n(m+x) > m(n+x) = nm+nx> mn+mx
Now subtracting mn on both sides, it becomes nx > mx,
Divide by x on both sides it becomes n>m
Hence statement 1 is sufficient, pls explain why this is is not possible.
