Question 12

Q12)A Motorcycle runs 31\frac{1}{4} km consuming 1 litre of petrol. How much distance will it run consuming 1\frac{3}{5} litre of petrol ?

Solution :

It is given that the Distance covered by the motorcycle in 1 litre of petrol = 31\frac{1}{4}km =\frac{125}{4} km

∴ Distance covered by the motorcycle in 1\frac{3}{5} litre of petrol

=\frac{125}{4}\times1\frac{3}{5}

=\frac{125}{4}\times\frac{8}{5}

=\frac{10000}{20}

=50km

Hence,50 km will be covered in 1\frac{3}{5} litre of petrol.
