Answer:
let sp of a pen be x
loss=20%
then CP = ( SP * 100 ) / ( 100 – percentage loss )
= x*100/80
=1.25x
Again
if sp= x=10
then profit =5%
CP = ( SP * 100 ) / ( 100 + percentage profit )
= (x+10)*100/105
= 20x+200/21
as cp is equal
1.25x= (20x+200)/21
26.25=20x+200
6.25x=200
x=32
Step-by-step explanation:
rs 200 since the questions states that if he sold it for 10 more, he would have gained 5%, 10=5% 1%=2 100%=200
