when IAM calculating income from long term capital gain I come accross 3 ways of taxability. they are as follows.
1) long term capital gain exempt u/s 10 (38)
2) long term capital gain which is taxable @ 10% without indexation
3) long term capital gain @ 20% with indexation

can anyone help when the long term capital gain is taxable under each of the above catagories? & what are the conditions to be satisfied for each of the above catagories?
