Rights Issue tax

I want to understand tax on rights issue.

Especially rights issue with multiple money calls.
Example an rights issue of rs1000.

With rs250 money call with 4 calls. How is it taxed.

I buy rights share in nse, then I get money call and I pay it and later I sell it.

So is can I add money call price with cost of share when I brought as cost of acquisition.
