Question 1086983: Steven is 4 times as old as his son. In another 4 years he will only be 3 times older than his son. How old is Steven now Answer by ikleyn(52788) (Show Source):
Let x be the son's present age.
Then the father's present age is 4x years.
In 4 years, the son's age will be x+4 yeras, while the father's ge will be 4x + 4.
The condition says
4x+4 = 3*(x+4).
Simplify and solve it:
4x + 4 = 3x + 12 ====> x = 12 - 4 = 8. Thus the son's present age is 8 years.
Then the father's present age is 4*8 = 32 years.
