Ramesh marks his article at Rs 6000 and after allowing a discount of 20%, he still earns 60% profit. What is the cost price (in Rs) of the article?

Let the cost price = Rs. $$100x$$

=> Selling price = $$100x+\frac{60}{100}\times100x=Rs.$$ $$160x$$ ----------------(i)

Also, Marked price = Rs. 6000 and discount % = 20%

=> Selling price = $$6000-\frac{20}{100}\times6000=6000-1200=Rs.$$ $$4800$$ ------------(ii)

From equations (i) and (ii), we get :

=> $$160x=4800$$

=> $$x=\frac{4800}{160}=30$$

$$\therefore$$ Cost price = $$100\times30=Rs.$$ $$3000$$

=> Ans - (C)
