LTCG or STCG on Bonus Shares?

Please help me out with this conundrum

I had X shares of RIL which had a Buy date of 20140423

Now I had 2X shares & the share price was halved,

First X shares have a Buy date of 20140423


Second X shares have a Buy Date of 20170909

I sold the shares in Nov. 2017

Now according to the date of allotment,

The first X shares fall under Long Term


The second X, ‘The bonus shares’ fall under Short Term.

Will i have to pay 15% as STCG on the sale of the second X ?

Yes. The cost of purchase of bonus shares should be considered as 0 and STCG of 15% is applicable on the profits.
