Answer 1

Let the present age of Amon’s son be x years.

Therefore, Aman’s age = 3x years.

According to question,

$3x-10=5\left(x-10\right)3x−10=5(x−10)</p><p></p><p>\Rightarrow3x-10=5x-50⇒3x−10=5x−50</p><p></p><p>\Rightarrow3x-5x=-50+10⇒3x−5x=−50+10</p><p></p><p>\Rightarrow\ -2x=-40⇒ −2x=−40</p><p></p><p>\Rightarrow x=\frac{-40}{-2}=20⇒x= </p><p>−2</p><p>−40</p><p></p><p> =20 years</p><p>$

=20 years

Hence, Aman’s son’s age = 20 years

And Aman’s age = 3 x 20 = 60 years.
