Let the cp be rs x. if a man gains 20% profit by selling an article for rs 816. find cp​

Let, the c.p be x.

Given,

profit % = 20%

S.P = rs 816

c.p = x

We know,

profit = p% of c.p

         = * x

         =

now,

   C.p = profit + s.p.

        x = + 816

        x =

       5x = x + 4080

       5x-x = 4080

       4x = 4080

         x =

         x = Rs 1080

Hence, the c.p is Rs. 1080
