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:

Aman’s son’s age = 20 years

Aman’s age = 3 x 20 = 60 years.

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.

Answer 2

Step-by-step explanation:

Aman age = 3x-10

son age = x-10

3x-10= 5(x-10)

3x-10 = 5x-50

.2x = -40

aman = 60

• son = 20
