. A car can cover a distance of 357 km on 42 litres of petrol. How far can it travel on 12 litres ofpetrol?

Answer»

Distance covered by the car with 42 L of petrol = 357 km

Distance covered by the car with 1 L of petrol = 357/42 km [less petrol, less distance]

Now, distance covered by the car with 12 L of petrol = 357/42×12 = 102 km [more petrol, more distance]
