From Barter to MoneyClass 7 Social Science NCERT Solutions

The barter system is a way of exchanging goods and services without using money. People directly exchange goods or services for other goods or services. A variety of commodities were used for exchange under the barter system, including cowrie shells, salt, tea, tobacco, cloth, cattle (cows, goats, horses, sheep), and seeds.

The barter system had several limitations. One major problem was the double coincidence of wants, which means that both parties must want what the other has to offer. Another issue was the lack of a common standard measure of value, making it difficult to determine fair exchange rates. The problem of divisibility also arose when goods could not be easily divided. Portability was another limitation, as carrying bulky goods was inconvenient. Finally, durability was a problem because some goods could rot or spoil over time.

Ancient Indian coins were made from precious metals like gold, silver, and copper, or their alloys. They were called kārṣhāpaṇas or panas and had symbols punched on them called rūpas. Different kingdoms had their own coinage, and the minting and issue of coins were controlled by the rulers. The coins had different symbols and motifs engraved on them, including nature motifs like animals, trees, and hills, as well as images of kings, queens, and deities. The coins of powerful rulers were accepted across various kingdoms, facilitating trade across geographies.

Money has transformed significantly over time. Initially, the barter system involved direct exchange of goods and services. Then, various commodities like cowrie shells and cattle were used as a medium of exchange. Coinage, made from precious metals, emerged as a more standardized form of money. Paper money was introduced later to overcome the difficulties of carrying and storing coins. Today, digital money, including debit cards, credit cards, net banking, and UPI, is widely used, allowing for electronic transactions. This evolution reflects the need for more efficient, portable, and durable forms of money.

To make Indian coins a medium of exchange across countries in ancient times, several steps could have been taken. Ensuring the coins had a consistent weight and purity of metal would build trust. Establishing trade agreements with other kingdoms to recognize the value of Indian coins would be beneficial. Displaying symbols of widely recognized deities or rulers on the coins might increase their acceptance. Maintaining political stability and economic strength would also enhance the credibility of Indian coinage. The coins of powerful rulers were accepted across various kingdoms and not just their own. This facilitated trade across geographies.

The statement that an annual salary of 60 panas could be substituted by an āḍhaka of grain per day suggests that one pana had a significant value, enough to provide a substantial amount of food. The fine for failing to help a neighbor being 100 panas, which is more than the annual salary, indicates that community support and cooperation were highly valued. This suggests that the society encouraged people to prioritize helping each other, and placed a high penalty on neglecting communal responsibilities, reflecting a strong emphasis on social harmony and mutual support.

This question requires a creative activity (writing and enacting a skit) and, therefore, does not have a specific solution based on the textbook content. The skit should demonstrate how people might have convinced each other to accept cowrie shells as a medium of exchange by highlighting their portability, durability, and agreed-upon value.

This question requires research beyond the textbook. The security features of Indian currency notes include watermarks, security threads, latent images, micro lettering, and intaglio printing. These features make it difficult to counterfeit the notes. The RBI also uses special paper and inks to enhance security. These measures are designed to ensure the integrity of the currency and prevent its misuse.

This question requires conducting interviews and gathering information from family members and local shopkeepers. The answers will vary based on individual preferences and experiences. Some may prefer cash for its simplicity and directness, while others may favor UPI for its convenience, speed, and ability to track transactions electronically. The reasons for their preferences may include factors such as ease of use, security concerns, and access to technology.
