The percentage change in the diamond rings price was 200%.
Given:
The price of a diamond ring was reduced by 80% then went up by 200%.
To find:
What was the percentage change in the diamond rings price
Solution:
Let the price of ring be x,
Price of ring reduced by 80% = x-80% of x
= x - (80x/100)
= (100x - 80x)/100
20x/100
Price of ring when increased by 200% = 20x/100 + 200% of 20x/100
= (20x/100) + (200/100 * 20x/100)
= (20x/100) + 40x/100
= (20x + 40x ) / 100
= 60x/100
Percentage change = [(60x/100 - 20x/100) / (20x/100)] * 100
= 40x/20x * 100
= 2 * 100
= 200%
The percentage change in the diamond rings price was 200%.
