Ten years ago,a man is three times as old as his nephew.In five years,he will be four times as old as his nephew. How old is his nephew?

Sagot :

ten yrs ago, man will be 3x while his nephew will be x. five years from now, man will be 4x while the nephew would be x. again.

3x+15 (because 10 and 5 yrs) is equal to 4x.
then, it will become 15=4x-3x, or simply, 15=x.
the nephew is 15 years old.
