Every Year Before The Festive Season,a Shopkeeper Increases The Price Of The Product By 35% And Then Introduce Two Successive Discount Of 10% And 15% Respectively.what Is Percentage Loss And Percentage Gain?

Answer»

LET cp= 100,

35 % increase in sp=135

10 % discount in 135((135*10)/100)=13.5

so 1ST sp=(135-13.5)=121.5, again 15 % discount in 1st sp((121.5*15)/100)=18.225

2nd sp=(121.5-18.225)=103.275,

so finally cp=100,sp=103.275 ,GAIN by 3.27%.
