Question 1010628: a man is five times as old as his son. in two years time he will be four times as old as his son. find their present age Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Call their ages NOW, m and s. Then
m = 5s and in two years
m + 2 = 4(s + 2)
Substitute the first into the second and get
5s + 2 = 4s + 8
s = 6
m = 30
