Correct Answer - Option 4 : 100 min
Given:
Yukta while going to the market reduces his speed to 5/6th of her actual speed
Calculation:
Let Yukta actual speed is 6 unit/min and reduces her speed to 5 unit/min
⇒ Actual speed ∶ Reduced speed = 6 ∶ 5
We know that time is inversely proportional to speed
⇒ Reduced Time ∶ Actual Time = 6 ∶ 5
There is 1 unit difference of time is 20 minutes.
1 unit = 20 minutes
⇒ 5 units = 5 × 20 = 100 minutes
∴ Yukta's actual time to reach the market is 100 minutes.
