Question:

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

(a) 100 litres

(b) 50 litres

(c) 25.16 litres

(d) 25 litres

Solution:

(a) 100 litres

Explanation: Distance covered by truck using 54 litres diesel = 297 km
