Question

pls answer correctly in paper​

Answer 1

Answer:

sp=300

profit%=20%

(profit/cp)×100=20

{(sp-cp)/cp}×100=20

100sp-100cp=20cp

100×300=20cp+100cp

120cp=30000

cp=30000/120

cp=250

Answer 2

SP= 300
Profit=20%
CP= ?

Lets take the CP as 100 so,
Profit=20%
SP= 100 + 20
= 120

we know that SP = 300
So 300=120

As CP, we estimated = 100
So,
300 x 100/120
=250

So CP = ₹250
