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 the petrol costs Rs 44 per litre, how much did he spend in all on petrol?
Solution –
Quantity of petrol filled by the taxi driver on Monday = 40 litres
Quantity of petrol filled by the taxi driver on the next day = 50 litres
Cost of petrol per litre = Rs 44
Total quantity of petrol filled by him = 40 + 50
= 90 litres
Total amount spent on petrol = Rs (44 × Total quantity of petrol filled by him)
Rs (44 × 90)
= Rs 3,960
Hence, taxi driver spent Rs 3,960 in all on petrol.
