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

Let the price of oranges (last year) be x
Price of oranges (this year) be y

$x+y+ \frac{(x)(y)}{100}$
$24+50+ \frac{(24)(50)}{100}$
$= 74+12 = 86$

Answer 2

hello!

Last year,12 oranges cost Rs.24
1 orange cost Rs (24÷12)
=2
This year,20 oranges cost Rs.50
1 orange cost Rs.(50÷20)
=2 1/2

therefore, the difference b/w the price of orange in the two years
=Rs. (2 1/2-2)
=Rs.1/2

therefore, percentage increase
= {(1/2÷24)×100}%
={(1/2×1/24)×100}%
={1/48×100}%
=2 11/12 % (Answer).
