Question

A washing machine was marked 40% above cost price and a discount of 35% was given on its marked price find his gain or loss percent

Answer 1

let the cost price of the machine be x.

then marked price = x + x*40/100  =140x/100 =7x/5

after giving discount of 35% on the marked price, the selling price is   7x/5   *   65/100   = 91x/100 

selling price =91x/100    it is less than CP so there is a loss

loss % = (CP - SP)/CP    *100 =  (x - 91x/100)/ x    *100  =   (9x/100)/x   *100 =  9/100   *100  =  9

so there is 9% loss.

Answer 2

Answer:

let the cost price of the machine be x.

then marked price = x + x*40/100  =140x/100 =7x/5

after giving discount of 35% on the marked price, the selling price is   7x/5   *   65/100   = 91x/100  

selling price =91x/100    it is less than CP so there is a loss

loss % = (CP - SP)/CP    *100 =  (x - 91x/100)/ x    *100  =   (9x/100)/x   *100 =  9/100   *100  =  9

so there is 9% loss.
