Question

Aman's age is three times his son age . ten years ago he was five times his son's age . find thier present age​

Answer 1

Answer:

Let the present age of Amon's son be x years. Therefore, Aman's age = 3x years. And Aman's age = 3 x 20 = 60 years.

Answer 2

Answer:

The present ages of Aman and his son are 60 years and 20 years respectively.

Step-by-step-explanation:

Let present age of Aman's son be x years.

From the first condition,

Aman's present age = 3 * Son's present age

∴ Aman's present age = 3x years

Now,

Ten years ago age of son = ( x - 10 ) years

And ten years age of Aman = ( 3x - 10 ) years

From the second condition,

Aman's age = 5 * Son's age

⇒ ( 3x - 10 ) = 5 ( x - 10 )

⇒ 3x - 10 = 5x - 50

⇒ - 10 + 50 = 5x - 3x

⇒ 40 = 2x

⇒ 2x = 40

⇒ x = 40 ÷ 2

⇒ x = 20 years

∴ Son's present age = 20 years

Now,

Aman's present age = 3x

⇒ Aman's present age = 3 * 20

⇒ Aman's present age = 60 years

∴ The present ages of Aman and his son are 60 years and 20 years respectively.
