Pinky fills her car tank with 20 liters of petrol. She goes on a journey and ends up with just 5.5 liters of petrol left in the tank. What is the percent change in the petrol in the tank?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 72.5 percent.
Total petrol in the tank = 20 liters
Remaining petrol after the journey = 20 - 5.5 = 14.5 liters
Percentage change in the petrol = Petrol consumed/Total petrol × 100
= 14.5/20 × 100 = 72.5%
