Question

find cp of S.P. =
712.50, Loss = 5%​

Answer 1

Answer:

let us suppose tge C.P be (x)

Loss= C.P - S.P

or, 5/100*x= x-712.50

or, x/20= x- 712.50

or, x=(x-712.50)20

or, x=20x - 14250

or, 21x= 14250

or,x = 678.5714286

C.P = 678.5714286

Answer 2

Step-by-step explanation:

s.p=712.50

loss=5%

c.p=?

as we know that,

loss%={(c.p-s.p)/c.p}×100

5/100=(c.p-712.50)/c.p

1/20=(c.p-712.50)/c.p

c.p/20=(c.p-712.50)

c.p=20(c.p-712.50)

c.p=20c.p-14250

19cp=14250

therefore cp=14250/19=750 rupee
