Understanding the Car's Remaining Petrol After a Trip

In this article, we will explain how to calculate the amount of petrol left in a car after a trip, using a step-by-step approach. We'll go through various solutions and common methods to ensure a thorough understanding of the concept.

Initial Condition

Let's start with the initial condition: the car has 32 liters of petrol before the start of the trip. If the car uses 75% of the petrol, we need to calculate the remaining amount of petrol in the car.

Step-by-Step Calculation

Calculate the amount of petrol used:

Petrol used 75% of 32 liters 0.75 x 32 24 liters

Calculate the amount of petrol left:

Petrol left Total petrol - Petrol used 32 liters - 24 liters 8 liters

So, there are 8 liters of petrol left in the car after the trip.

Alternative Solutions

Let's consider different ways to calculate the remaining petrol:

Calculation 1:

Petrol in car before the start of the trip 32 liters

The car consumes petrol during the trip 75% of 32 liters

The car consumes petrol during the trip 75/100 X 32 24 liters

Petrol left in the car 32 - 24 8 liters

Calculation 2:

75% of 32 liters is 24 liters

Therefore, 8 liters should be left after the trip

Calculation 3:

75 of the petrol having been used leaves us with 25 of it (25% of the petrol is left)

25 is one fourth so it is 25% of 32 liters 32 divided by 4 8 liters left

Conclusion

By following these steps, you can easily calculate the amount of petrol left in your car after a trip. Understanding the percentage of petrol used and the calculation methods will help you manage your fuel usage effectively.

It is important to keep track of your car's fuel consumption and plan your trips accordingly to avoid running out of petrol in the middle of a journey.
