Question

Ramesh buys a pen for Rs 20 and sells it at 20% profit. For what price should
he buy it so that he can make 25% profit by selling for the same selling price.
​

Answer 1

CP of pen =₹20
Profit%=20%

Profit% = profit*100/CP
20 = profit *100/20
20*20/100=profit
Profit =₹4

Profit =SP-CP
4=SP-20
SP=₹24

Let new CP be ₹x
Profit %=25%
SP=₹24

Profit %= profit *100/x
25= profit *100/x
25x/100=profit

Profit =SP-CP
25x/100=24-x
25x/100+x=24
125x/100=24
5x/4=24
x=24*4/5
x=₹19.20
