Detailed Solution
Download Solution PDFGiven:
Pinky bought 25 books at the rate of ₹14 each, 40 pens at the rate of ₹7 each and 15 pencils at the rate of ₹6 each.
Formula used:
Average price = (Total cost of all items) / (Total number of items)
Calculation:
Total cost of books = 25 × 14 = ₹350
Total cost of pens = 40 × 7 = ₹280
Total cost of pencils = 15 × 6 = ₹90
Total cost of all items = 350 + 280 + 90 = ₹720
Total number of items = 25 + 40 + 15 = 80
Average price = Total cost of all items / Total number of items
⇒ Average price = 720 / 80
⇒ Average price = 9
∴ The correct answer is option 2.
