Question

Q13) A man is three times as old as his son. After 5 years, the ratio of their
ages will be 5:2. Find their present ages.​

Answer 1

Answer:

30 years more than son's age.

Explanation:

Let the son's age be x.

man's age =3x

∴3x−5=4(x−5)

or 3x−5=4x−20

or 20−5=4x−3x or x=15

After 5 years, son's age is x+5=15+5=20.

man's age is 3x+5=45+5=50 which is 30 years more than son's age.
