Verified Answer
A car owner buys diesel at Rs.7.50, Rs. 8 and Rs. 8.50 per litre for t...
Total quantity of petrol consumed in 3 years =(4000/7.50+4000/8+4000/8.50)  liters
= 4000(2/15+1/8+2/17) liters                                                   
= 76700/51 liters
Total amount spent = Rs. (3 x 4000) = Rs. 12000.
Average cost = Rs. (12000*51/76700) = Rs. 7.98.

Calculation:

- Total amount spent over 3 years = Rs. 4000 x 3 = Rs. 12000
- Total quantity of diesel purchased over 3 years = Rs. 12000 ÷ Rs. 7.50 + Rs. 8 + Rs. 8.50 = 1600 + 1500 + 1400 = 4500 litres
- Average cost per litre = Total amount spent ÷ Total quantity of diesel purchased
- Average cost per litre = Rs. 12000 ÷ 4500 = Rs. 2.67

Therefore, the average cost per litre of diesel is approximately Rs. 7.98. This calculation takes into account the varying prices of diesel over the three years and provides a more accurate representation of the average cost.
