Question

A taxi driver 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 petrol costs ₹ 44 per litre, how much did he spend in all on petrol?

Answer 1

Quantity of petrol filled on Monday = 40 l

Quantity of petrol filled on Tuesday = 50 l

Total quantity filled = (40 + 50) l

Cost of petrol (per l) = ₹ 44

Total money spent = 44 × (40 + 50)

= 44 × 90

= ₹ 3960
