Solution:Legal tender is a coin or a banknote that is legally tenderable for discharge of debt or obligation. In other words, legal tender money is a form of money recognized by law as a means to settle a public or private debt or to meet a financial obligation, including tax payments, contracts, and legal fines or damages. Hence, it is the money which a creditor is under compulsion to accept in settlements of his claims. The metallic money (coins) in circulation in a country is part of legal tender which includes banknotes also. But, there may be some limitations (as in India) for coins to be legal tender in payment.The coins issued by Government of India under Section 6 of The Coinage Act, 2011, shall be legal tender in payment or on account provided that a coin has not been defaced and has not lost weight so as to be less than such weight as may be prescribed in its case. Coin of any denomination not lower than one rupee shall be legal tender for any sum not exceeding one thousand rupees. Fifty paise (half rupee) coin shall be legal tender for any sum not exceeding ten rupees. While anyone cannot be forced to accept coins beyond the limits mentioned above, voluntarily accepting coins for amounts exceeding the limits mentioned above is not prohibited.
Every banknote issued by Reserve Bank of India (Rs. 2, Rs. 5, Rs. 10, Rs. 20, Rs. 50, Rs. 100, Rs. 200, Rs. 500 and Rs. 2000), unless withdrawn from circulation, shall be legal tender at any place in India in payment or on account for the amount expressed therein, and shall be guaranteed by the Central Government, subject to provisions of sub-section (2) Section 26 of RBI Act, 1934. Rs. 1 notes issued by Government of India from time to time are also legal tender.
