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. (1score=20 ) ....

Answer 1

cost of 1 orange last year = 24/12= Rs. 2
cost or 1 orange this year= 50/20= Rs. 2.5
Percentage change = ((2.5-2)/2) x 100= 25%
So there is 25% increase in the price compared to last year.

Answer 2

In last year,

Cost of 1doze = 12orange = Rs24

=> Cost of 1 orange = 12/24 =Rs2

In this year,

Cost of 1score = 20oranges = Rs50

=> Cost of 1 orange = 20/50 = Rs2.5

Hence, increase in price % = 2/2.5−2 × 100 = 25 %
