Question

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

• A. 50%
• B. 40%
• C. 60%
• D. 80%

Answer 1

The correct option is C

60%

The cost of 12 oranges last year = Rs 72

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

The cost of 20 oranges this year = Rs 48

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

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

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