I have bought a mobile phone of M.R.P. Rupees.13999. The demand for phone is very much and stock from company is less and so people who have got this mobile are selling it for price more than 13999 and making profits. My question is that can I also sell the mobile for more price it the buyer is willing to buy and give more money? thanks.

If both are agreed and buyer is aware of the price and happy to pay an extra amount then it is allowed but profit must not be very high.
