A crockery store offered a sale of 15% on their products. If a specifi [#permalink]
A crockery store offered a sale of 15% on their products. If a specific product was already on 10% sale, what is the percent decrease from the original price before any discount to the current price?

Let the original price be 100.
After 10% discount, price was changed to 90.
After another 15% discount, price was changed to .85*90 =76.5

Total decrease in price from 100 to 76.5 = 23.5
=> total %age change = 23.5%

Let Original price: 100

Already on 10% sale: 100 * $$\frac{90 }{ 100}$$ = 90

Sale of 15%: 90 * $$\frac{85 }{ 100}$$ = 76.5

Percent decrease: $$\frac{(76.5 - 100) }{ 100}$$ * 100 = 23.5
