Dear sir
One of my friend while trying to fill the ITR through online, what date of purchase and the buying price to be filled in the concerned column of Capital gain? He already demate his shares. Those shares were purchased 10 to 15 years back. The concerned details were not available (ie., the date of purchase and price etc.,) So the Grand father date and price can be taken as date of purchase and price in ITR. Please kindly help.
