# Crore|Definition & Meaning

## Definition

In the **South Asian numbering system**, **crore** is a value **equivalent** to **ten million** value in the **International numbering system.** It can also be denoted in the form of **10$^7$** in **scientific notation.** It is written as **1,00,00,000** in the South Asian numbering system, which is denoted as **10,000,000** in the international numbering system.

Unlike the **three-digit separator technique** in the **international numbering system,** the **South Asian countries** adopt a **2-2-3 separation method** hence the crore is having 7 zeros with 3 then 2 and 2 digit separators. This numbering system is usually implemented in South Asian Countries that include **Pakistan, India, Bangladesh, Nepal, Myanmar, Srilanka, Bhutan, and Afghanistan. **

## The South Asian Numbering System

The **South Asian Numbering System** is a numbering system that is adopted by South Asian countries that include Pakistan, India, Bangladesh, Nepal, Myanmar, Srilanka, Bhutan, and Afghanistan, to express **large numbers.** It is unique in the usage of **2** **digit separator** after the thousand value instead of the 3-digit separators used in the international numbering system.

Furthermore, this numbering system uses the words **“lakh”** “crore” **“arab”** and **“kharab”** to denote **large sums** **of numbers.** This numbering scheme has been used since the **Vedic Age** (c. 1500 – c. 500 BCE). These have been a **convention** for the local people and have continued to use since then.

The term **“lakh”** is used to denote values that in the **International numbering** **system** would be equal to **one hundred thousand**. A hundred thousand number is denoted as **“100,000”** whereas, in South Asian numbering, lakh is denoted as **“1,00,000.”** We can observe the use of digit separators grouped for 2 numbers after the initial three-number grouping.

Moreover, the term **“crore”** has been used to denote values equal to **ten million** in the international numbering system. It is represented as **1,00,00,000** in the South Asian system as compared to the ten million, **10,000,000.** It is a very easy-to-use convention used in the **Indian subcontinent.**

### History of the South Asian Numbering System

South Asian numbering system dates back to the early **Vedic** **Age,** where this was a common usage of defining large values. They have been since using this numbering system and is widely accepted in the Indian Subcontinent over the usage of the international numbering system. **Sri Lanka** has **adopted** the International numbering system but the rest of the Indian subcontinent still **abides** by its **conventions** and **culture.**

Moreover, the terms Lakh and Crore are derived from the **Sanskrit** names **“Laksha”** and **“koti”** respectively. They then mixed with other variants over time such as **“krodi”** in the **Prankit language** to become the words that we listen to in the current time.

Furthermore, there are more **names** with **higher values than crore** given in the South Asian Numbering system is different from the usual International numbering system. The **figure** below shows the values greater than a crore and has their names with the **scientific value** in the **standard form** beside it.

## Examples Depicting the Usage of Crore and South Asian Numbering System

Below are a few examples showing how the south Asian numbering system is utilized in calculations and representing answers that contain large values.

### Example 1

A lump of coal has a **heating** value of **30000kJ/kg** for a **600 kW** coal-fired power plant. If the **efficiency** of the plant is** 25%,** find the total amount of coal supplied to the power plant in one hour and calculate the cost of the coal considering the cost of coal is Rs **200/kg.**

### Solution

In this problem, we are given a heating value of **30000 kJ/kg** for a **600 kW** power plant. First, we need to find the **total input power** of the power plant by dividing the efficiency by the rated value of the power plant:

**Input power of the power plant** = $\dfrac{600}{0.25}$

**Input power of the power plant** = 2000 MW

**Input power of the power plant** = 2000 x 10$\mathsf{^3}$ kW

Now, we need to find the **amount** **of** **coal** used to run this power plant **per second.**

**Coal Required (in kg/sec)** = $\dfrac{2000 \times 10^3}{30000}$

**Coal Required** = 66.67 kg/s

Now, the coal required for** one** **hour** of running the **power plant** will be equal to:

**Total Coal Required** = 66.67 x 3600

**Total Coal Required** = 240000 kg

So, we require **240000** kg of coal to run this power plant for one hour. Let us calculate the **total cost** it takes to buy this amount of coal.

**Cost of Coal** = 240000 x 200

**Cost of Coal** = Rs. 48000000

Hence, the total cost of coal is **Rs. 4,80,00,000,** which can be said as **4 crore 80 lakh rupees** worth of coal was used to run a coal-fired power plant for one hour.

### Example 2

A salesman buys a large mansion for **Rs.** 15 **crore** (Rs. **15,00,00,000)** and lives in it for 2 years. After that, he **sells** the mansion for **Rs 13 crore and 50 lakh (Rs. 13,50,00,000)**. The annual tax he paid was at the rate of** 3% of the cost** of the mansion. Find the **loss** amount that the salesman faced.

### Solution

The tax **incurred** to the salesman on **buying** the **Rs. 15,00,00,000** mansion is calculated as:

**Tax of mansion for 2 years** = 150000000 x 0.03

**Tax of mansion for 2 years** = Rs. 4500000

Hence, the **tax** is** Rs. 45,00,000** or **Rs. 45 Lakh. **

The **total loss** of the salesman over two years can be calculated as:

**Total Loss **= 150000000 – 4500000 – 135000000

**Total Loss** = Rs. 10500000

Thus, the **total loss** of the salesman is **Rs. 1,05,00,000** or** Rs. 1 crore** and** 5 lakh.**
