Question 1064296: a man is 4 times as old as his son . After 16 years he will be only twice as old as his son fnd their present age Answer by addingup(3677) (Show Source):
You can put this solution on YOUR website! f = 4s
f+16 = 2(s+16)
f+16 = 2s+32
4s+16 = 2s+32
2s = 16
s = 8 the son is 8
and the father:
f = 4s = 4(8) = 32 the father is 32.
-------------------------------------
In 16 years:
father: 32+16 = 48
son . : 8+16 = 24 and twice as old as the son: 24*2 = 48 Correct!
