​

Answer 1

Given:-

• Anil is 4 years older than Sunil.

• 8 years ago ratio of Anil and Sunil ages was 3 : 1.

To Find:-

• Their Present ages are,

Solution:-

Here, Let the age of Sunil be $x$ years.

Then age of Anil is $x + 4$ years.

Now, 8 years ago ratio of Anil and Sunil ages was 3 : 1.

Therefore, $\dfrac{(x + 4) - 8}{x - 8} = \dfrac{3}{1}$

             ⇒ $\dfrac{x + 4 - 8}{x - 8} = \dfrac{3}{1}$

             ⇒ $\dfrac{x - 4}{x - 8} = \dfrac{3}{1}$

             ⇒ $1(x - 4) = 3( x - 8 )$

             ⇒ $x - 4 = 3x - 24$

             ⇒ $3x - x = 24 - 4$

             ⇒ $2x = 20$

             ⇒ $x = \dfrac{20}{2}$

             ⇒ $x = 10$

Hence, Present age of Sunil is 10 years.

And, Present age of Anil is ( 10 + 4 ) = 14 years.
