CALCULATIONS:⇒ Let, the cost price of ARTICLE = x⇒ Selling price of article = 84x/100 = 21x/25loss% = [(cost price - selling price)/100] × 100⇒ Loss% = (x - 21x/25) × 100/x⇒ 16%⇒ New cost price = 120x/100 = 6x/5⇒ New selling price = 21x × 125/25 × 100⇒ New selling price = 21x/20loss% = (cost price - selling price) × 100/cost price⇒ Loss% = (6x/5 - 21x/20) × 100/6x/5⇒ Loss% = 12.5 %⇒ Decrease in losses = (16 - 12.5) × 100/16⇒ \(% MathType!MTEF!2!1!+- % feaahqart1ev3aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn % hiov2DGi1BTfMBaeXatLxBI9gBaerbd9wDYLwzYbItLDharqqtubsr % 4rNCHbGeaGqiVu0Je9sqqrpepC0xbbL8F4rqqrFfpeea0xe9Lq-Jc9 % vqaqpepm0xbba9pwe9Q8fs0-yqaqpepae9pg0FirpepeKkFr0xfr-x % fr-xb9adbaqaaeGaciGaaiaabeqaamaabaabaaGcbaaeaaaaaaaaa8 % qacaaIYaGaaG4mamaalaaapaqaa8qacaaIXaaapaqaa8qacaaI4aaa % aaaa!3958! 23\frac{1}{8}\)21.875%∴ The decrease in losses is 21.875%.
