ans [c] 120 litres

60x(800 km/600 km)x(1200 cc/800 cc) = 120 l

First lets find out for a 800 cc engine now. For an 800 cc engine,
diesel required to cover 600 km = 60 litres
Thus diesel required for 800 km = 60/600 * 800 = 80 litres

Now, diesel required to cover 800 km using 800 cc engine = 80 litres
Thus, diesel required to cover 800 km using 1200 cc engine = 80/800 * 1200 = 120 litres
