Question

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

Answer 1

Answer:

Let, the c.p be x.

Given,

profit % = 20%

S.P = rs 816

c.p = x

We know,

profit = p% of c.p

         = $\frac{20}{100}$ * x

         = $\frac{x}{5}$

now,

   C.p = profit + s.p.

        x = $\frac{x}{5}$ + 816

        x = $\frac{x+ 4080}{5}$

       5x = x + 4080

       5x-x = 4080

       4x = 4080

         x = $\frac{4080}{4}$

         x = Rs 1080

Hence, the c.p is Rs. 1080
