Answer 1

Let his son's age be x

Aman’s age → 3x (Three times his son's age)

10 years ago,

son's age → x - 10

Aman’s age → 3x - 10

Now, as per the Question, he is five times his son’s age.

= 3x - 10 = 5(x - 10)

= 3x - 10 = 5x - 50

= 2x = 40

= x = 20

Therefore, their ages are:

Aman →60 years

His son’s age → 20 years

Answer 2

$\huge{\boxed{\tt{Answer:-}}}$

Let the age of son be x

Aman's age = three times of his son age = 3 * x = 3x

10 years ago

Son's age = x - 10

Aman's age = 3x - 10

$\huge{\boxed{\tt{Explanation:-}}}$

★ Given:-

5 times son's age 10 years ago = Aman's age 10 years ago

⇒ 5(x - 10) = 3x - 10

⇒ 5x - 50 = 3x - 10

⇒ 5x - 3x = - 10 + 50

⇒ 2x = 40

⇒ x = 40/2

$\large{\boxed{\tt{⇒ x = 20}}}$

Present age of son = x = 20 years.

Present age of Aman = 3x = 3(20) = 60 years.

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