Question

After allowing a discount of 10% on the marked price ,a trader still make a gain of 17%.By what per cent of marked price above the cost price

Answer 1

Gain = 17% = 17/100

ie Selling price = 100 + 17 = 117

Market price = y

y x 90/100 = 117

y = 1170/9 = 130

profit ie market proce above CP = 130 - 100 = 30

Perecent of market price above CP = 30/100  x 100  = 30%
