Tax on ltcg

Hello Friends, Shares sold in stock exchange where STT is paid and is a LTCG means acquired 20 years back but now sold, for eg bought at 10/- par value in 1995 and now in 2015 sold at 250/- arises 2 queries

(a) Income out of above transaction has to be shown in ITR2 under Exempt income LTCG row or I have to show all this under the Capital Gains sheet.

(b) Do these value have to be indexed or shares sold in BSE are not indexed. Thanx
