Dear Priyanka,
I am sure that you know well that a Public Ltd Company registered under the Companies Act,1956 can engage itself in any business, trade,service or manufacturing of its choice and the suffix attached to it as per its name clause refers to its constitution only. Therefore, without knowing the nature of its activity for which people are employed, one can not answer your question. Also, you can get the details of minimum wages for your industry by going through the web portal of the Labor Department of the concerned State or Central Govt as the case be.
