Answer 2

✬ Son = 20 Years ✬

✬ Father = 80 Years ✬

Explanation:

Given:

• Present age of father is four times age of his son.
• After 10 years father's age will be three times the age of his son.

To Find:

• What is the present age of father and son ?

Solution: Let the present age of son be x years. Therefore,

➟ Present age of father = 4 times of x

➟ Father = 4x years

[ After 10 years their ages will be ]

• Son's age = (x + 10) years
• Father's age = (4x + 10) years

A/q

• After 10 years father's age will be three times the age of his son.

$\implies{\rm }$ 4x + 10 = 3(x + 10)

$\implies{\rm }$ 4x + 10 = 3x + 30

$\implies{\rm }$ 4x – 3x = 30 – 10

$\implies{\rm }$ x = 20

So, Present age of

➨ Son is x = 20 years

➨ Father is 4x = 4(20) = 80 years
