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
Distance covered by truck using 1 litre diesel = 297/54 = 5.5 km
Hence, for 550 km, diesel required = 550/5.5 = 100 litres
