Question

Last year, oranges were available at Rs. 24 per dozen; but this year, they are available at Rs. 50 per score. Find the percentage change in the price of oranges.

Answer 1

Price of 1 orange = `(24)/(12)` = Rs.2

New price = `(50)/(20)` = Rs.2.50   ...[∵ 1 score = 20]

Increase in price  = Rs.2.5 - Rs.2.0 = Rs. 0.50

∴ % Change in price (increase)

= `(0.50)/(2) xx 100  = 0.50 x 50 = 25%`
