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.
Price of 1 orange = 2412 = Rs. 2
New price = 5020=Rs.2.50[∵1score=20]
Increase in price = Rs. 2.5 - Rs. 2.0 = Rs. 0.50
∴ % Change in price (increase)
= .502×100=0.50×50 = 25%
