Answer:
Correct option is
C
Aman's age: 60 years; Aman's sons age: 20 years
Let Aman's son age =x
Aman's age =3x
Ten years ago, he was 5 times the age of his son.
Therefore, 3x−10=5(x−10)
3x−10=5x−50
2x=40
x=20
Aman's son is 20 yrs old
Aman is 3x=3×20=60 yrs old.

Step-by-step explanation:
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)
\Rightarrow3x-10=5x-50⇒3x−10=5x−50
\Rightarrow3x-5x=-50+10⇒3x−5x=−50+10
\Rightarrow\ -2x=-40⇒ −2x=−40
\Rightarrow x=\frac{-40}{-2}=20⇒x=
−2
−40
=20 years
Hence, Aman’s son’s age = 20 years
And Aman’s age = 3 x 20 = 60 years
