What to do?

First we have to find the amount of petrol bought in these two days. Then, we have simply multiply it with the cost/litre in order to calculate the total money spent in it.

Amount of Petrol bought:

• 20 litres in first day.
• 35 litres in second day.

Total amount of Petrol bought = 20 + 35 l = 55 l

Cost of petrol:

(Per litre = ₹72)

⇒ Total cost = 55l × ₹72/l

⇒ Total cost = ₹3960

Hence,

Total cost of petrol for two days: ₹3960
