Given; the ratio of the ages of father and son at present is 4:1, after 6 years the ratio will become 5:2
To Find; the present age of the son
Solution; Let the age of the son =x
Then the age of the father = 4x
Age of father after 6 years = 4x+6
Age of son after 6 years = x+6
Ratio of age after 6 years =5/2
2(4x+6)=5(x+6)
8x +12 = 5x +30
3x =18
x= 6
Hence the present age of son is 6 years
