A man purchased 3 bags of cement at the rate of ₹2,200 each, 4 bags of cement at ₹2,550 each and 5 bags of cement at the rate of ₹3,120 each. What is the average cost of one bag of cement?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e ₹2,700.
3 bags at ₹2200 each → 3 × 2200 = 6600
4 bags at ₹2550 each → 4 × 2550 = 10200
5 bags at ₹3120 each → 5 × 3120 = 15600
Total cost = 6600 + 10200 + 15600 = 32400
Total bags = 3 + 4 + 5 = 12
Average cost per bag = 32400 ÷ 12 = ₹2700
