Question

The cost price of an article is 30 percent more than its selling price.Find its profit or low as percent

Answer 1

The cost price of an article is 30 percent more than its selling price
let cost price be CP and selling price be SP

so, CP = SP + 30% SP
CP = 100%SP + 30% SP
CP = 130% SP

so, to obtain Selling price

original price = (increase percentage/whole increase) × 100

SP = CP - (30/130) × 100 of CP
SP = CP - 23.07%CP
SP = 130% - 23.07% of 130%
SP = 130% - (.2307)130%
SP = 130% - 30%
SP = 100%

so, total loss is 23.07%
