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,
