The barter system is an old system of exchanging money. Here students will learn about the barter system meaning, the barter system example, barter system activity for class 4. Also, it contains details about what is the barter system and its shortcomings. The mathematical concept of rupeespaise and pictograph is connected with this content.
What is Barter System?
A century ago, there was no money. So, how did people buy and sell at that time?
It all started with the barter system. Imagine, in a kingdom, there were people with different types of work, like cobblers, farmers, trailers, etc.
Barter System
Suppose Ram is a farmer and Rahul is a cobbler. When Rahul needs vegetables, he approaches Ram and exchanges a pair of slippers for the vegetables he needs. It is known as a Barter system.
But the barter system works in the double coincident principle. Here, two coincidences have to happen.
Barter System Examples:
If Rahul needs a haircut and he goes to Pritam, the barber, but the value of the hair cut much lesser than the value of the slipper, and the slipper cannot be divided; hence no barter takes place. Thus, the exchange of goods is not easy. Then the barter system converts to money.
After the covert system, profit and loss also can find in the new system.

Counting Money
Question 1:
Riya Goes to the Market to Buy a Few Pens. Find the Cost of 10 Pens in Rupees, If the Cost of 1 Pen Is 16 Anna.
Answer 1:
Here given, the cost of 1 pen is 16 annas.
Then, the cost of 10 pens is
= (10 × 16) anna
= 160 annas
Now, we know that 16 annas = 1 rupees
Then, 160 annas = 16016 rupees = 10 rupees
The cost of 10 pens is 10 rupees.
Convert Paise Into Rupees
Question 2:
Sumit Buys Some Goods From a Shop, and the Price Is Given As:
Then He Converts the Price Into Rupees and Buys This. What Is the Total Amount in Rupees?
Answer 2:
We know that 100 paise = 1 rupees
So, 10000 paisa = 10000100 rupees = 100 rupees
And also, we know that 16 annas = 1 rupees
So, 48 anna = 4816 rupees = 3 rupees
then, the total amount is = (100 + 3) rupees = 103 rupees
Sumit buys the chocolate and ice cream for 103 rupees.
Question 3:
Ram Exchanged a Slipper With Some Milk. If the Price of the Milk Is 45 Rupees. Then Represent 45 Rupees As the Sum of 20 Rupees and 5 Rupees Notes and Convert 45 Rupees Into Annas.
Answer 3:
Here, 45 rupees can be represented as:
We know that 16 annas = 1rupee
So, 45 rupees = 45 × 16 annas
= 720 annas
Hence, 45 rupees = 720 annas
Question 4:

Answer 4:
 Moni give three pairs of shoes to Debu for one dress
 The student gave the lunch lady 10 rupees for cookies.

Question 5:
If We Put the Given Element in a Barter System, Find Out What Can Be Exchanged With Each Other With the Same Value.
Answer 5:
We know 1 rupee = 100 paise
Then, 2 rupees = (2 × 100) paise = 200 paise
So, apples can be exchanged for bananas.
Also, we know that 16 annas = 1 rupee
Then, 25 rupees = (25 × 16) anna = 400 anna
So, mango can be exchanged for the book.
Pictograph Question for Class 4
Question 6:
In a Vegetable Shop, Shop Kipper Counted the Price That Sold in a Whole Day for Different Vegetables and Recorded It in a Pictograph.
Read the Chart Given Below and Answer the Following Question:
Vegetable  Price 

Potato 

Tomato 

Brinjal 

Pumpkin 

 What Is the Value of Potatoes?
 Find the Value of the Tomato and Represent the Value As the Sum of Notes and Coins.
 What Is the Price Difference Between Brinjal and Pumpkin?
Answer 6:

Here value of 1 symbol = 1 rupee
Value of 10 symbol = (10 × 1) rupees
= 10 rupees.
Hence, the value of the given potato is 10 rupees. 
Here value of 1 symbol = 1 rupee
Value of 12 symbol = (12 × 1) rupees
= 12 rupees
Half of the symbol = half of 1 rupee
1 rupee = 100 paisa
Half of the symbol = (12 × 100) paisa
= 50 paisa
Total = 12 rupees + 50 paisa
= 12.50 rupees.
Hence, the value of the given tomato is Rs 12.50. 
Here value of 1 symbol = 1 rupee
Value of 15 symbol = (15 × 1) rupees
= 15 rupees
Half of the symbol = half of 1 rupee
1 rupee = 100 paisa
Half of the symbols = (12 × 100) paisa
= 50 paisa
Value of brinjal = 15 rupees + 50 paisa
= 15.50 rupees.
Value of 21 symbol = (21 × 1) rupees
= 21 rupees
Half of the symbols = (12 × 100) paisa
= 50 paisa
Value of pumpkin = 21 rupees + 50 paisa
= 21.50 rupees
Hence, the price difference between brinjal and pumpkin is 6 rupees.
