Correct Answer - Option 2 : 40

**Given**

Rajesh is 10 years younger to Baskar, 10 years back, Rajesh's age was two thirds that of Baskar's.

**Concept used**

Ratio and proportion

**Calculation**

Let the present age of Baskar be x years.

Rajesh's present age = x - 10

10 years back, Rajesh's age was two thirds that of Baskar's.

⇒ \(x - 20 = \frac{2}{3}\left( {x - 10} \right)\)

⇒ 3x - 60 = 2x - 20

⇒ x = 40

Baskar is of 40 years now.
