e have a client, whose annual turnover is around ₹25.00L. This is what usually shown in returns.
A year back they had given money to A of ₹25.00L in cash. Now A is going to invest that money in some housing project as approved by Central Government and our client will be partner in that. So they have to show money in white around 25-50L. Plz tell me how can they show it ? I had these ideas :
1. To take a loan from some other person through cheque. What can be consequences of this ? Is it safe ? 
Plz guide me in this regard.
