Income Tax on Profit from Shares?

My father had invested around 3 lakhs in the shares of a Private Limited Nursing Home in 1990. The present cost of the shares is around 30 lakhs. After the death of my father, the shares were transferred in the name of my mother. If the shares are now sold, will my mother have to pay any income tax on the profit? If yes, what are the possible ways to evade it?

How profit earned on a flat booking taxed?

I had booked a flat in the year 2007. After that construction started. The construction is now complete. I wish to sell the same to a buyer even before the flat being registered in my name, i.e. the sale deed will be between me, the builder, and the buyer, which will be executed in Feb 2012. I will earn some amount from this sale. How the income tax will be levied on this transaction. Whether it will be a capital gain, and if so, short term or long term?
