Question

If SP is equal to rupees 400 and loss percent is 20% find CP​

Answer 1

Explanation:

Given,

S.p.=Rs400

Loss percent(L%) =20%

C.p.=?

We know,

S.p. =(100-L) % of c.p.

or,400=(100-20)% *c.p.

or,400=80% *c.p.

or, 400=80/100*c.p.

or,c.p.=Rs.500

Here, c.p.=Rs.500

Answer 2

• SP=400
• Percentage of loss=20%

100-20=80%=400

`\\ \rm\longmapsto 80\%\:of\:CP=400`

`\\ \rm\longmapsto CP=400* (100)/(80)`

`\\ \rm\longmapsto CP=5(100)`

`\\ \rm\longmapsto CP=500`
