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 rupees-paise 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.

**Subdivisions of the Rupees During the 20th Century:**

Value (in anna) | Popular name | Value (in paise) |
---|---|---|

16 anna | 1 rupee | 100 paise |

8 anna | 1 athanni | 50 paise |

4 anna | 1 pavala | 25 paise |

2 anna | 1 beta | 12 paise |

1 anna | 1 ekanni | 6 paise |

## 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:

Read the Incidents Carefully and Circle the Correct System of Exchange.

- Moni Give 3 Pairs of Shoes to Debu for One Dress
- The Student Gave the Lunch Lady 10 Rupees for a Cookie
- Jon Exchanges His Sunglass With Rabi’s Bag.

Barter or Money

Barter or Money

Barter or Money

### Answer 4:

- Moni give three pairs of shoes to Debu for one dress
- The student gave the lunch lady 10 rupees for cookies.
- Jon exchanges his sunglass with Rabi’s bag.

## 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.
