A Shopkeeper sells an article at rs 300 thus earning a profit of 20%.find the cost price of an article.

$\small\green {Solution:}$]

We are given, SP = 300

And Profit = 20%

We know that Profit% = Profit*100/CP

So, 20*CP = 100*Profit

so, Profit = CP/5

So, SP-CP = CP/5

So, 300 = CP/5+CP

SO, 6CP = 1500

So, CP = 250 rs
