Question

The cost of petrol is 60 per litre. A petrol bunk sells 750 litres of petrol on a day. How much money do they get at the end of the day?

Answer 1

Hint: Firstly, we assume the cost of petrol is ‘x’ per litre, then the cost of ‘m’ litres petrol will be ‘mx’.

Complete step-by-step answer:
Here, given the cost of petrol is 60 units per litre.
\[\therefore \]The cost of one litre petrol is 60 units.
Here, also given, the petrol bunk sells 750 litres petrol in one day.
Therefore, the money they get at the end of the day, will be,
   = (Cost of one litre petrol) x (the total amount of petrol sold in one day ) units
   =(60 x 750) units
   =45,000 units

Note: Here, you have to remember that the money that they get at the end of the day is equal to the total cost of the petrol sold on a day.
In addition, you have to notice that no currency is mentioned here. So, you have to put ‘units’ as the currency whether it is not mentioned.
