The importance of money flows from it being a link 
between the present and the future.

In the theme “Tapestry of the Past”, you read about the crops 
that people grew, such as food grains or goods they made like 
carnelian beads. How do you think they exchanged these 
goods for things that they needed?

People exchanged goods or services for other goods and 
services. This system is called the barter system. How did 
this work? Suppose you need a pencil and have an extra 
eraser. Meanwhile, your classmate forgot to bring their 
eraser but has an extra pencil. You could exchange your 
extra eraser for the extra pencil that your classmate has. 
Wouldn’t this satisfy your and the classmate’s needs? This 
is how the barter system works. 
Today, we use coins and notes to buy and sell things. People 
also use their mobile phones and computers for such 
transactions.
The barter system was the earliest form of exchange. There 
is a lot of evidence of it from around the world.  People 
used commodities such as cowrie shells, salt, tea, tobacco, 
cloth, cattle (cows, goats, horses, sheep), seeds, etc. 
Transaction:

Why Do we Need Money? 
LET’S EXPLORE
Imagine that you are a 
farmer and that people 
use a barter system where 
you live. You need a whole 
variety of things — a pair 
of new shoes, a sweater, 
and medicines for your 
grandmother. But you only 
have an ox that you can 
spare. How would you be 
able to exchange the ox for 
all the different things you 
need from different people or 
places? What difficulties are 
you likely to face? 
For one, you would have to 
find someone who needed an 
ox. Now, swapping your ox for 
a pair of shoes would hardly be a fair exchange! You may have 
had to go through a series of exchanges — for example, find 
someone to exchange your ox 
for several bags of wheat. You 
would then have to transport 
all that wheat to several 
places; first, find someone 
willing to exchange a part of 
the wheat for shoes, another 
person for the sweater, and 
yet another for the medicines.

medicines — all in exchange for his ox. Do you think it 
would be easy to come across such a situation? 
Just like the farmer, people who depended on the barter 
system would face many problems in making an exchange 
in their everyday lives. They would have to find someone 
who wants the exact item that they want to give, and in 
return are also able to offer exactly what the other party 
wants. This scenario is called double coincidence of wants.  
Even if there are two people who want each other’s goods 
and are also willing to make an exchange, other issues 
could arise — in what proportion should the two goods be 
exchanged? In such cases, it becomes difficult to compare 
the value of one good against another. If one of the people 
feels that the exchange is disadvantageous, they would not 
be interested in the exchange. This is because there is no 
common standard measure of value.

a sweater; this is the problem of divisibility. Taking the 
ox everywhere is a problem and leads to the problem of 
portability.  You solved part of the problem by exchanging

FAQs on Class 7 Social Science Chapter 11 NCERT Book - From Barter to Money

1. What is barter and how did it function in ancient economies?
Ans. Barter is the direct exchange of goods and services without using money. In ancient economies, people would trade items they had for items they needed. For example, a farmer might exchange wheat for tools made by a blacksmith. This system relied on a mutual desire for the goods being exchanged, which made transactions simpler but often limited.
2. What are the limitations of the barter system?
Ans. The barter system has several limitations, including the need for a double coincidence of wants, meaning both parties must have what the other wants. Additionally, it is difficult to determine the value of goods, and bartering can be impractical for large transactions. This complexity led to the development of money as a more efficient medium of exchange.
3. How did money evolve from the barter system?
Ans. Money evolved from the barter system as people needed a more efficient way to trade. Initially, items such as shells, salt, or gold were used as a medium of exchange because they were widely accepted and had intrinsic value. Over time, these items were standardized into coins and later paper currency, which simplified transactions and allowed for easier trade over long distances.
4. What roles does money play in modern economies?
Ans. In modern economies, money serves several critical roles: it acts as a medium of exchange, a unit of account, and a store of value. Money facilitates trade by providing a common value for goods and services, allowing for easier pricing and budgeting. It also helps in saving and investment, as it can retain value over time.
5. Why is the concept of money important for economic growth?
Ans. The concept of money is crucial for economic growth because it allows for efficient trade, investment, and resource allocation. With money, businesses can easily transact, invest in new projects, and expand operations, leading to increased productivity. Moreover, money provides a reliable measure of value, which helps consumers and producers make informed economic decisions.
