5. 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 65 per litre, how much did he spend in all on petrol? ​

Answer 1

Answer:

Total petrol filled= 40+50 litres

                           = 90 litres

Cost of petrol=rs 65/litre

So total money spent in petrol= 65×90

                                                 =  5850

So he spent rs 5850 in petrol

Answer 2

Answer:

5850 rupees

Step-by-step explanation:

Cost of petrol per litre = 65

Cost of 40 litres of petrol on Monday = 40 x 65

Cost of 50 litres of petrol on Monday = 50 x 65

Total amount spent =

(40 x 65) + (50 x 65)

take 65 common

65(40 + 50)

65 x 90 = 5850 rupees
