Age Poblem with solution and meaning

Sagot :

 Ten years ago, John was four times as old as Bill. Now he is only twice as old as Bill. Find their present ages.

Solution:
 Let x= Bill's present age
 2x= John's age now
 x-10= Bill's age ten years ago
 2x-10 = John's age ten years ago

4(x-10) = 2x-10
 4x-40 = 2x-10
 4x-2x = -10 + 40
 2x = 30
 x= 14

 Bill's present age is 15 while John's present age is 30.


Enjoy doing homework! :))
