If 20% of 10% of a number is 12, what is 10% of 20% of the same number?
Accepted Solution
A:
There are 5 20% in 100% ( 20 x 5 = 100)So 10% of a number would be 12 x 5 = 60Then there are 10 10% in 100% ( 10 x 10 = 100). So if 10% = 60, then 100% = 60 x 10 = 600. The starting value is 600600 x 10% = 600 x 0.1 = 6060 x 20% = 60 x 0.2 = 12Now you have the starting value you can calculate the other answer:600 x 20% = 600 x 0.20 = 120120 x 10% = 120 x 0.10 = 12The answer would be 12
