$Given \ Problem$

A taxi driver filled his car petrol tank with 40 litres of petrol on Monday the next day he filter tank with 50 litres of petrol if the petrol cost rupees 44 litre how much did he spend in all on petrol​.

$Solution$

To Find:

Total cost of petrol filled.

According to your question:

Given that:

$=>Petrol\ price\ Rs.\ 44\ per\ liter.$

$=>50 \ liters \ of \ petrol \ on\ the\ next \day.$

$=>Petrol \ price\ Rs.\ 44 \per \ liter.$

$Method:$

$=>Total\ petrol\ filled\ by \ a \ taxi \ driver \ is \ the \ sum \ of \ petrol \ filled \ during \ both \ days$

$=>Total\ petrol\ filled\ = 40 + 50 = 90\ liters$

$=>So, the\total \petrol\ filled \by \a \taxi \drivers\ is \ 90\ liters.$

$=>Cost \ of \ 1\ liter \ of \ petrol = Rs. 44$

$=>To\ find \ the \ cost \ spent \ multiply \ total \liters \ and \ cost \ of \ one \ liter.$

$=>Cost\ of\ 90\ liters\ of\ petrol => 90 *44 = 3960$
