A trader marked up the price of a product by 75%. When the discount was decreased from 50% to 25%, his profit increased by rs.210. What is the cost of the product?

Yukta:,

Let the real price of product be X

Marked price=75%   3x/4

X+3x/4=7x/4

When the discount decreased from 50% to 25%  =25%

7x/4*25/100=7x/16=210

210*16/7=3360/7

Let the real price of the product be X

The marked price will be X+ 3X/4 = 7X/4

Now for selling purpose discount was set to 25%

i.e discount = 7X/4 * 25/100

Discount = 7X/16

Selling price = 7X/4 - 7X/16 = 21X/16

Profit = 21X/16 - X = 5X/16

We know profit is 210.

5X/16 = 210

X = 672.

Therefore the real price of the product is 672
