A dozen oranges cost ₹96, 2 dozen apples cost ₹240 and 4 pineapples costs ₹180. What is the average cost (in ₹) per piece?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e 12.9.
1 dozen oranges = 12 pieces = ₹96 ⇒ 1 orange = 96 ÷ 12 = ₹8
2 dozen apples = 24 pieces = ₹240 ⇒ 1 apple = 240 ÷ 24 = ₹10
4 pineapples = ₹180 ⇒ 1 pineapple = 180 ÷ 4 = ₹45
Total cost = 96 + 240 + 180 = ₹516
Total pieces = 12 + 24 + 4 = 40
Average = 516 ÷ 40 = ₹12.9 per piece
