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:
240
Petrol required = 540 / 45 = 12 litres.
The cost of petrol is Rs. 20 per litre, so the total cost is:
Cost = 12 * 20 = Rs. 240.
Therefore, the amount required for the journey is Rs. 240.
