Question

a father is 7 time as old as his son.two years age , the father ws 13 time old as his son. how old are they now
​

Answer 1

let the sons present age be x

then

then fathers = 7x

take them as ratio

x/7x

two years ago

x-2/7x-2=1/13

13(x-2)=7x-2

13x-26=7x-2

6x=24

x=4

son = 4

father = 28

hope it helps
