Plug in -

m + n = 3  Or,  1 + 2 = 3

And,  \frac{n}{m} = 2  Or,  \frac{2}{1} = 2

Henc,  n = 2  , Answer must be (E)

ScottTargetTestPrep · Answer

We can rewrite the second equation as n = 2m. Substituting 2m for n in the first equation, we have:

m + 2m = 3

3m = 3

m = 1

Thus, n = 2.

Answer: E

n/m=2 =>n=2m

As, m+n=3

therefore, 
m+2m=3
=> 3m=3 
thus, m=1
