Mr. X applied for a lot and a lot is allotted to Mr. X

Another investor Mr.B also wants a lot of company A before listing as he expects that company will list at a higher price than the issued price. 

So he deals with Mr. X to get transferred Mr. X allotted shares to his Demat account by giving 150 per share to Mr. X.
