What is the numerical value of the expression (2m n + m)/(n m)?

Question

What is the numerical value of the expression  \frac{2m – n + m}{ (n – m)} ?

(1)  \frac{2m }{n –m} = \frac{7}{3}

(2)  n – m = 6

SherzodAzamov · Answer

\frac{2m – n + m}{ (n – m)}  =  \frac{2m}{ (n – m)}  - 1

S1: Sufficient

S2: Not sufficient as we have two unknowns with 1 equation.

Answer A 
IMHO

Given, expression (2m–n+m)/(n–m) = 2m/(n-m) - 1 So, stat 1: gives the value of 2m/(n-m), which is sufficient to get value of expression. Stat2: n-m= value, not sufficient. So, I think A.
