stop the uses of 500 and 1000 notes , because all black money is available in these notes (check the CBI rades ) by that corruption is not stop by it becom toooo much low . if person wants 1 lac than he reciv 10 pkts of 100 rs notes OR 1 pkt of 1000 rs notes . soo its risky to reciv 10 pkts as compare to 1 pkt .
