If m varies directly as n and inversly as o, and m=20 when n=50 and o=10, find m when n=96 and o=16.
m= kn/o
Need to find "k"
20=k(50)/10
k=4
Equation: m = 4n/o
Now find m when n=96 and o=16.
m=4(96)/16
m=4(6)= 24

m is proportional to , so that , where k is a constant, to be found.

Given that m=20, n=50, o=10 then we have

--> k = 20/5
--> k = 4

So,

Hence, when n=96 and o=16 we get:
