Solution
A truck needs 54 litres of diesel for covering a distance of 297 km. The diesel required by the truck to cover a distance of 550 km is 100 litres.
Explanation:
Distance covered by truck using 54 litres diesel = 297 km
Distance covered by truck using 1 litre diesel = `297/54` = 5.5 km
Hence, for 550 km, diesel required = `550/5.5` = 100 litres
