Correct Answer - Option 2 : 40 minutes

**Given: **

Shruti drive in both ways in 20 minutes

She drives one way and walks back in 30 minutes

**Calculation:**

Drive from point A to B + Drive from point B to point A = In 20 minutes

Drive both ways in 20 minutes

Drive one way in 10 minutes

Drive from point A to B + Walk from point B to A in 30 minutes

⇒ 10 minutes + Walk from point B to A = In 30 minutes

⇒ Walk-in one way = 20 minutes

Walk from point A to B + Walk from point B to A = 20 minutes + 20 minutes = 40 minutes

**∴ The time is taken by Shruti is 40 minutes**
