Question 7

# A motor cycle gives an average of 45 km per litre. If the cost of petrol is Rs. 20/litre. The amount required to complete a journey of 540 km is, (in Rupees)

Solution

The bike runs for 45 km in 1 litre of petrol

Cost of petrol = Rs. 20/litre

Thus, petrol required for covering 540 km = $$\frac{540}{45}=12$$ litres

$$\therefore$$ Amount required to complete a journey of 540 km = $$12 \times 20$$

= $$Rs.$$ $$240$$

=> Ans - (D)
