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

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.
