Question

Last year the cost of oranges was ₹72 per dozen. This year the price is ₹48 per score. Find the percentage change in the price of oranges. (1 score = 20 units)

• A. 50%
• B. 40%
• C. 60%
• D. 75%

Answer 1

The correct option is C

60%

The cost of 12 oranges last year = ₹72

The cost of 1 orange last year = $\frac{72}{12}=₹6$

The cost of 20 oranges this year = ₹48

The cost of 1 orange this year = $\frac{48}{20}=₹2.4$

Difference in price per orange = ₹6 - ₹2.4 = ₹3.6

$\therefore$ Percentage change = $\frac{3.6}{6}\times 100=60\%$
