Question

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

Answer 1

Let, the c.p be x.

Given,

profit % = 20%

S.P = rs 816

c.p = x

We know,

profit = p% of c.p

=
`(20)/(100)` * x

=
`(x)/(5)`

now,

C.p = profit + s.p.

x =
`(x)/(5)` + 816

x =
`(x+ 4080)/(5)`

5x = x + 4080

5x-x = 4080

4x = 4080

x =
`(4080)/(4)`

x = Rs 1080

Hence, the c.p is Rs. 1080
