If m>0 and x is m percent of y, then in terms of m, y is what percent of x?

x = (m/100)y

y = (100/m)x

But the OA is 10,000/ m.

Why do you have to multiply it by 100 ?

you almost got there

y = (100/m)x

which means y=(10000/m) % of x

Take example

y = (100/m)x

Take y =50 m=10 x=5

So 50 is (10000/10) % of 5

ie 50 is 1000% of 5 (50/5 * 100 = 1000)

Hope u got it...Use #s

If m>0 and x is m percent of y, then in terms of m, y is what percent of x?

x/y *100 = m ie: ym = 100x then y/x = 100/m thus y/x*100 = 100^2/m

Given

x= m/100 *y thus y= 100*x/m
y =100*x/mx *100=100^2/m

Tough though on actual test day. I don't think i'll have time to pick #s to check my answers ...
