petrol?​

Answer 1

Total quantity of petrol used by the taxi driver = 40 + 50 = 90 liters

Cost of 1 liter of petrol = Rs 44

Cost of 90 liters of petrol = 44 x 90 = Rs 3960

Hence, the required amount is Rs 3960

Answer 2

Step-by-step explanation:

Petrol filled on Monday = 40 liters

Petrol filled on next day = 50liters

Total petrol filled = 90liters

Now, Cost of 1 liter petrol = Rs. 44

Cost of 90 liters petrol = 44 x90

= 44 x (100 – 10)

= 44 x 100 – 44 x10

= 4400 – 440

= Rs. 3960

Therefore, he spent Rs. 3960 on petrol.
