Short term capital gains tax

Hello friends

One  query please.

Say , I purchased 100 qty of shares at rate Rs. 100 / share. (  In addition to this there is Brokerage = 40 , service tax of say Rs. 20 and STT = 40 ------ Total other charges = 100 ) .

Total Value of transaction is Rs. 100 x 100 = 10000 /- + 100 = 10100.

I sell all the shares within one year at the rate of Rs. 200 per share. (  In addition to this there is Brokerage = 80 , service tax of say Rs. 40 and STT = Rs.80 ---------- Total other charges = 200 ) .

Total Value of transaction is Rs. 200 x 100 = 20000 /- + 200 = 20200.

Please help in calculating the capital gains tax. ( Please ignore Transaction charges , stamp duty etc )

Regards

Kiran
