The small denomination currency i.e. the notes of Rs. 5 , Rs. 10 , Rs. 20 and coins are not very easily available in the market.Nobody is willing to give you change very easily.For example if you have to pay a bill of say Rs. 616 and you give note of Rs. 1000 to the seller then either he will refund you only Rs. 380 or refuse to sell unless you bring the change of Rs. 16.
Every year RBI issue these notes and coins but theses are not flowing in the market. Where these currency notes are going and how they are made out of the economy.
