Fr urgent doubt

Yes, you have to take into account the convertible preference shares while calculating the % of holding. Pls check this link and read my reply there for further details. /forum/companies-act-2013-effect-on-financial-reporting-nov-2014-301628.asp#.VUJTq9Kqqko

Yeah u are right..That is what I meant. And in case the question doesnt mention whether the preference shares are convertible or not, u can just write an assumption that the preference shares are non-convertible and solve the problem as per AS 21 by ignoring preference shares.
