Question

Jasleen marks her goodsat 30% above the cost price and allows a discounr of 25% on the markef price.find her gain or loss percent

Answer 1

let the cost price be x
then MP=x+30*x/100
            =x+3x/10=13x/10
discount =20% of MP
              =20/100*13x/10
              = 13x/50
SP=13x/10-13x/50
    =(65x-13x)/50
    =52x/50
Profit=52x/50-x
         =2x/50
Profit % = (2x/50)*100/x
              = 4%
