A taxidriver filled his car petrol tank with 40 litres of petrol on Monday. The next day, he filled the tank with 50 litres of petrol. If the petrol costs ₹ 44 per litre, how much did he spend in all on petrol?
Petrol quantity filled on Monday = 40 litres Petrol quantity filled on Tuesday = 50 litres Total petrol quantity filled = (40 + 50) litre Cost of petrol per litre = ₹ 44 Total money spent = 44 × (40 + 50) = 44 × 90 = ₹ 3960
