3. Worked Example

Example 1: Calculating GDP Growth Rate

Year	GDP (₹ crore)
2022	70,000
2023	73,500

Growth Rate Formula
[ \text{Growth Rate} = \frac{\text{GDP}{2023} - \text{GDP}{2022}}{\text{GDP}_{2022}} \times 100 ]

Calculation [ \frac{73,500 - 70,000}{70,000} \times 100 = \frac{3,500}{70,000} \times 100 = 5% ]

Interpretation – The economy grew by 5 % in 2023.

Example 2: Computing Inflation Using CPI

Year	CPI
2022	250
2023	262.5

Inflation Rate Formula
[ \text{Inflation} = \frac{\text{CPI}{2023} - \text{CPI}{2022}}{\text{CPI}_{2022}} \times 100 ]

Calculation [ \frac{262.5 - 250}{250} \times 100 = \frac{12.5}{250} \times 100 = 5% ]

Interpretation – Consumer prices rose by 5 %.

Example 3: Real GDP

Assume:

Nominal GDP (2023) = ₹90,000 crore
GDP Deflator (2023) = 120 (price index)

[ \text{Real GDP} = \frac{\text{Nominal GDP}}{\text{Deflator}/100} = \frac{90,000}{1.20} = 75,000 \text{ crore} ]

Interpretation – After adjusting for price changes, real output is ₹75,000 crore.
