This is for

dave13GIVEN: x percent of y percent of z is t

Find values for t, x, y and z that satisfy the statement.

How about: 20 percent of 50 percent of 60 is 6

So, one solution is x = 20, y = 50, z = 60 and t = 6

So, when x = 20, y = 50 and t = 6, then

z = 60Now let's plug x = 20, y = 50 and t = 6 into each answer choice and see which one evaluates to be

60(C)10,000t/xy = 10,000(6)/(20)(50) = 60,000/1,000 =

60BINGO!!

Answer: C

Cheers,
