A shopkeeper purchases 5 cartoons in 105 rupees and 8 cartoons in 155 rupees. If a cartoon contains 5 items then average price per item is _____?

Explanation

Total cartons = 5 + 8 = 13

Total cost = 105 + 155 = 260

Total items = 13 x 5 = 65

Average price per item = Total cost / Total items = 260 / 65 = 4
