Question

the ratio between the present ages of p and q is 3:4 respectively if q's present age is 20 years what will be the ratio of the ages after 5 years? Full solution

Answer 1

let p present age be 3x
let q present age be 4x

so 4x=20
so x=5

so p 's present age is 15
after 5 years p will be 20 and q will be 25

so the ratio will be

20:25 ie 4:5
