Calculation of Average Rate of Petrol per Year

To find the average rate of petrol per year, we need to calculate the total amount of petrol bought and divide it by the total amount spent on petrol over the three years.

Given:
- Rate of petrol in the first year = 7.50 rupees per liter
- Rate of petrol in the second year = 8.00 rupees per liter
- Rate of petrol in the third year = 8.50 rupees per liter
- Amount spent on petrol per year = 4000 rupees

Calculating the Total Amount of Petrol Bought
To calculate the total amount of petrol bought, we divide the amount spent on petrol by the rate of petrol for each year.

Year 1:
Amount spent on petrol = 4000 rupees
Rate of petrol = 7.50 rupees per liter
Total amount of petrol bought in the first year = 4000 / 7.50 = 533.33 liters (approx.)

Year 2:
Amount spent on petrol = 4000 rupees
Rate of petrol = 8.00 rupees per liter
Total amount of petrol bought in the second year = 4000 / 8.00 = 500 liters

Year 3:
Amount spent on petrol = 4000 rupees
Rate of petrol = 8.50 rupees per liter
Total amount of petrol bought in the third year = 4000 / 8.50 = 470.59 liters (approx.)

Calculating the Average Rate of Petrol per Year
To calculate the average rate of petrol per year, we divide the total amount spent on petrol over the three years by the total amount of petrol bought.

Total amount spent on petrol = 4000 + 4000 + 4000 = 12000 rupees
Total amount of petrol bought = 533.33 + 500 + 470.59 = 1503.92 liters (approx.)

Average rate of petrol per year = Total amount spent on petrol / Total amount of petrol bought
Average rate of petrol per year = 12000 / 1503.92 ≈ 7.98 rupees per liter

Conclusion:
The average rate of petrol per year is approximately 7.98 rupees per liter.
