Question

if the selling price of a matress id 5400₹ and the loss percentage is 40% let us find the cost price​

Answer 1

Answer:

C.P = ₹9000

Step-by-step explanation:

Let C.P = 100% = x

∴ S.P = (100-Loss)%

         = (100-40)%

         = 60% of x = ₹5400

∴ 60x/100=5400

∴ x = 5400×100/60

     = 90×100

     = ₹9000

∴ Cost price = ₹9000
