Question

Last year, oranges were available at Rs. 24 per dozen; but this year, they are available at Rs. 50 per score. Find the increase in percentage of the price of oranges 1 score = 20.

Answer 1

In last year,
Cost of $1dozen=12oranges=Rs24$
=> Cost of $1$ orange $=\frac{24}{12}=Rs2$
In this year,
Cost of $1score=20oranges=Rs50$
=> Cost of $1$ orange $=\frac{50}{20}=Rs2.5$
Hence, increase in price % $=\frac{2.5-2}{2}\times 100=25$ %
