Solution

Petrol filled on Monday =40 litres

Petrol filled on the next day (Tuesday) =50 litres

Cost of 1 litre of petrol =Rs. 44

Now, the amount spent in overall petrol =Rs. (44×(40+50))

=44×90
=44×(10010)

Since, Distributive property over subtraction:

a×(bc)=(a×b)(a×c)

44×(10010)

=44×10044×10

=4400440

=3960

Therefore, he spent Rs. 3960 on petrol.
