Question

Rajan purchased a purse at 25% discount on its marked price but sold it at the Marked price.find the gain percent of Rajan and this translation

Answer 1

let the marked price be x:
discount of 25%, therefore purchase price is 75/100x = 0.75x
  Profit = selling price -buying ( we know price selling price = marked price)
          = x- 0.75x    
          =0.25x
gain % =  profit/ buying price(100)
         = 0.25/0.75(100)  =1/3(100)
         =33.3333%

Answer 2

let the marked price be x
discount = 25% therefore the the the purchased price 75x/100 = 0.75x
profit = selling price -purchase price
  x-0.75
= 0.25
gain % =sp-cp*100
             therefore the answer is 33.333%
