If the price of a product is first increased by 15%, and then decreased by 20%, then what is the percent change in the price?

5 decrease 8 increase 5 increase 8 decrease

8 decrease

Let the price = 100x Increase of 15% = 100x + 100x ×\(\frac{15}{100}\)  = 115x Decrease of 20% = 115x  × \(\frac{80}{100}\) = 92x Overall increase = 100x - 92x = 8x Required percentage = \(\frac{8x}{100x}\) × 100 = 8%
