The relationship between quantities m and n is expressed by the equation 10m = 5(n - 42). If the difference between the two chosen values of n is 30, what is the difference in the corresponding values of m?	Pick one:
A) 30/11
B) 42/11
C) 60/11
D) 150/11
E) 15
Another Simple way   10m=5(n-42)   Assume n = 42 to make one side equal to 0   then 10m=0   and m = 0   Repeat it by assuming n as 42+30 i.e 72   10m= 5(72-42)   10m=150   m=150/10=
