Now to your main questions
1::U hold 100 shares of RNRL ...For that ull get 25 shares of rel power ....For every 4 shares of RNRL 1 share of rel power..And RNRL will cease to exist
2::U not getting any bonus .Shares are getting swapped on contrary RNRL shareholders are on fault...Say u bought 100 shares of RNRL at 70 buks..so total u paid is 7000...Now ull get 25 shares of rel power on its place...So 25 shares of rel power which is trading around 180 which means...ull hold enitity worth 4500 rupees instead of 7000...Beacuse of same reason price of RNRL corrected..from 63 to 45-46..Because whoever buys RNRL share will get rel power which is trading at at 175-180 level....so 45 *4 180 price...
If rel power price goes to 200 ull see RNRL trading at 50
3::Rel cap ventures was swapped similarly to reliance capital now And rel energy ventures was merged or swapped to rel power
