Hi! I think i can answer your first question.
Antony Waste Handling Cell owns 63.04% in Antony Lara Enviro Solutions Private Ltd and 81.15% in Antony Lara Renewable Energy Private Ltd. I think when accounting, the total profits from the subsidiary is calculated and then the share of profits to other share holders of these subsidiaries is subtracted as minority interest/non-controlling interest. Hence the 23.5Cr. in total PAT - 5.5Cr. in minority interest, netting18Cr.
Do let me know if I have it wrong!
