On Monday, during a one day sale, the price of a suit was decreased by 20%. On Tuesday, the price of the suit was changed back to the original amount. By what percent did the price of the suit change on Tuesday?

Answer:25%Step-by-step explanation:If we consider the original price of the piece of suit is x. Given that, on Monday during a one day sale, the price of the suit was decreased by 20%. Therefore, the new price of the suit on Monday is [tex]x( 1 - \frac{20}{100}) = 0.8x[/tex]. Now, the price of the suit on Tuesday was changed back to the original price i.e. x. Therefore, the price is increase by (x - 0.8x) = 0.2x from the price of 0.8x. So, the percentage change in price of the suit on Tuesday is [tex]\frac{0.2x}{0.8x} \times 100 = 25[/tex]%. (Answer)
