# Question no. 5

Discount = 20%

Discount in rupees = Marked price * Rate of discount / 100

= 280 * 20 /100

= 5600 /100

= 56

So, Selling Price would be 280 - 56 = 224

Assume that the Cost Price is 100

Then Rate of profit is 12% So, Selling price will be 112

So, if selling price is 112, cost price is 100

if selling price will be 224, What will be the cost price?

So C.P. = 224 * 100 / 112

= 22400 / 112

= 200

So, cost price of the article is rupees 200.
