Question

Aman's age is three times his son's age. Ten years ago he was five times his son's age. Find their present ages​

Answer 1

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.

Answer 2

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
