Afather is four times as old as his son. in 4 years, the father will be three times as old as the son. how old is each now?

answer:

present age

let the sons age be x

then fathers age= 4x

after 4years

sons age= x+4

athers age = 4x+4

but given after 4 years

sons age = x+4

fathers age = 3(x+4)

4x+4 = 3(x+4)4x+4 = 3x+ 124x-3x=12-4x=84x= 4*8  =32

therefore present age of son is 8 years and father   is 32 years

hope i
