Question

A dozen oranges cost ₹96, 2 dozen apples cost ₹240 and 4 pineapples costs ₹180. What is the average cost (in ₹) per piece?

• A. 12.6
• B. 16.2
• C. 19.2
• D. 12.9

Answer 1

Answer:

D. 12.9

First find total cost and total number of fruits.

• 1 dozen oranges = 12 → cost = ₹96

• 2 dozen apples = 24 → cost = ₹240

• 4 pineapples = 4 → cost = ₹180

Total fruits = 12 + 24 + 4 = 40
Total cost = 96 + 240 + 180 = ₹516

Average cost per fruit = $( \frac{516}{40} = 12.9 )$

₹12.9 per piece
