Increase in paid up share capital - allotment of shares

Dear All,

We have to increase Paid up share capital ot the Company for which allotment is required to be made. 

In this case which method should be adopted? Private Placement or Right Issue?

Allotment would be as follows :

Out of 49000shrs 25000 to existing Director/Shareholder and 24000shrs to new Director

Is private placement preferable
