Mad Ade's uncle, Rod Wolloper, has 4 sons. In 13 years the combined ages of the four sons will be 96. So what would their combined ages be in just 7 years?

### Answer

72, each year the combined ages of the sons increases by four.So 13 years =96yrs

13yrs - 7yrs = 6yrs

6yrs * 4yrs = 24yrs

96yrs - 24yrs = 72 yrs

Average age 13 years from now is 96/4 = 24 years old, so their average age at start is 24-13 = 11 years old. In 7 years, they'll all be 11+7=18 years old, and 18x4 = 72.

Why is it that sillywilly always has to make even the most straight forward thing sound like a corkscrew?
