Answer» Given, There are 100 pens of Rs. 10 and 600 pencil of Rs. 5 and 120 notebooks of Rs. 25 : ⇒ Total COST of 100 pens = 100 × 10 = Rs. 1000 ⇒ Total cost of 600 pencil = 600 × 5 = Rs. 3000 ⇒ Total cost of 120 notebooks = 120 × 25 = Rs. 3000 The average cost of all items AVAILABLE in a Stationery shop: Average = (total cost of items)/number of items ⇒ Total cost of 100 pens, 600 PENCILS and 120 notebooks = Rs. (1000 + 3000 + 3000) = Rs. 7000 ⇒ Average cost of 100 pens, 600 pencils and 120 notebooks = (7000)/(100 + 600 + 120) = 7000 / 820 = Rs. 8.53 |
