💡 Analysis & Explanation
Total Expenditure Computation ▼
We systematically calculate the absolute total cost incurred across all categories. Cost of shirts = 8 * 550 = ₹4,400. Cost of pants = 10 * 1000 = ₹10,000. Cost of shoes = 12 * 850 = ₹10,200. Summing these values gives a grand total expenditure of 4400 + 10000 + 10200 = ₹24,600.
Total Quantity Calculation ▼
We must tally the total physical number of individual articles purchased: 8 (shirts) + 10 (pants) + 12 (shoes) = 30 absolute items.
Final Average Derivation ▼
The overall average cost per article is universally defined as Total Expenditure divided by Total Quantity. Thus, 24600 / 30 = 820.
Conclusion ▼
The accurately calculated average expenditure per single article is exactly ₹820.
