Question

Last year the cost of oranges was ₹ 72 per dozen. This year the price is ₹ 48 per Score. Find the percentage change in the price of oranges. (1 score = 20 units)

Answer 1

The cost of 12 oranges last year = ₹ 72

The cost of 1 orange last year
$=\frac{72}{12}=₹6$

The cost of 20 oranges this year = ₹ 48

The cost of 1 orange this year
$=\frac{48}{20}=₹2.4$

Difference in price per orange = ₹6 - ₹2.4 = ₹3.6

$\therefore$ Percentage change
$=\frac{3.6}{6}\times 100=60\%$
