The price of a dress is reduced

Question

The price of a dress is reduced by 20%. When the dress still does not sell, price was then reduced by 10% of the reduced price.If the price of the dress after both reductions is $264,what was the original price?

Answer 1

264 = 90%P

P = 264/.9 = 2640/9 = $293.33

Original Price = OP

80%OP = 2640/9

OP = 2640/9/.8= 2640/9 x 10/8 = 26400/72 = $366.67 = original price

20% off means 1/5 off 4/5(366.67) = $293.33

another 10% means 90% of $293.33 = $264
