Income tax filling

Hi, 

I have two questions I was doing business with partner which run into loss and we stopped . I am 54 years now. I am not working Since for last  2 years i have only interest income which is around 20000 and dividend around 40000 I had not filed any Tax return

This year I am planning to sell the share Bought in 1990 for 2 lakhs I may sell at near 10 lakhs.. 

Will there be a problem if I file  e tax.  Will I have to pay Income tax for the capital gains (This year also i will get 20000 interest and 25000 dividend

Please reply
