Question

S.p=315 loss percent =10% c.p=rs=xc.p=?​

Answer 1

Given:

S.P. = 315

Loss percent = 10%

To find:

The C.P.

Solution:

Let x be the C.P.

We have,

S.P. = 315

Loss percent = 10%

`S.P.=C.P.-10\%\text{ of }C.P`

`315=x-(10)/(100)x`

`315=x-0.1x`

`315=0.9x`

Divide both sides by 0.9.

`(315)/(0.9)=x`

`350=x`

Therefore, the cost price (C.P.) is 350.
