One day Garima was travelling back to her house on a scooter. She travelled a distance of 16 km in 4 litres of petrol. The next day she decided to go to museum which was 36 km far away from her house. How much petrol will she need to go to museum from her house?
9 litres
36 km can be travelled in (4/16) × 36 = 36/4 = 9 litres.
