Solution

Litres of petrol he filled on monday : 45 L
Litres of petrol he filled on next day : 35 L
Cost of petrol : Rs 68 per L
Total litres = 45 L + 35 L
Total cost =Cost per litre * Total litres of petrol
= (45 + 35) * 68
= 4568 + 3568
= 3060 + 2380
= Rs 5440
Hence, the total cost of petrol is RS 5440.
