Understanding economic and business news is essential for anyone preparing for competitive exams, especially in India where the economy plays a vital role in shaping daily life and national progress. Economic indicators like GDP, inflation, and unemployment rates provide a snapshot of the country's financial health. Government policies such as fiscal budgets, monetary measures by the Reserve Bank of India (RBI), and tax reforms like GST directly influence businesses and consumers alike.
Major business events, including mergers, stock market trends, and foreign investments, reflect the dynamic nature of the economy and its integration with global markets. Staying updated with these topics not only helps in answering current affairs questions but also builds a strong foundation for understanding how economic decisions impact society at large.
What is GDP? Gross Domestic Product (GDP) is the total market value of all final goods and services produced within a country during a specific period, usually a year. It is a key indicator used to measure the size and health of an economy.
GDP can be calculated using different approaches, but the most common is the expenditure approach, which sums up spending by various sectors.
The expenditure approach formula for GDP is:
Nominal vs Real GDP: Nominal GDP is measured using current prices, while Real GDP is adjusted for inflation, reflecting the true growth in production. Real GDP is a better indicator of economic progress over time.
GDP Growth Rate: This shows how fast the economy is growing and is calculated as the percentage change in Real GDP from one year to the next.
What is Inflation? Inflation is the rate at which the general level of prices for goods and services rises, causing purchasing power to fall. When inflation is high, each unit of currency buys fewer goods.
Consumer Price Index (CPI): CPI measures the average change over time in the prices paid by consumers for a fixed basket of goods and services. It is a key tool to calculate inflation.

The inflation rate is calculated as:
Impact of Inflation: Inflation reduces the purchasing power of money, affects savings, and influences interest rates. Moderate inflation is normal in a growing economy, but high inflation can hurt consumers and businesses.
Step 1: Calculate real GDP for each year by adjusting nominal GDP with the GDP deflator.
Real GDP = \(\frac{\text{Nominal GDP}}{\text{GDP Deflator}} \times 100\)
For 2022: \(\frac{200}{110} \times 100 = 181.82\) lakh crore
For 2023: \(\frac{220}{115} \times 100 = 191.30\) lakh crore
Step 2: Calculate growth rate using real GDP values:
\[ \text{Growth Rate} = \frac{191.30 - 181.82}{181.82} \times 100 = \frac{9.48}{181.82} \times 100 \approx 5.22\% \]
Answer: The real GDP growth rate from 2022 to 2023 is approximately 5.22%.
Step 1: Use the inflation rate formula:
\[ \text{Inflation Rate} = \frac{157.5 - 150}{150} \times 100 = \frac{7.5}{150} \times 100 = 5\% \]
Step 2: Interpretation: A 5% inflation rate means that on average, prices of consumer goods and services increased by 5% from 2022 to 2023.
Answer: Inflation rate is 5%, indicating moderate price rise affecting purchasing power.
Step 1: Calculate final price before GST hike:
\[ \text{Final Price} = 1000 \times \left(1 + \frac{12}{100}\right) = 1000 \times 1.12 = Rs.1120 \]
Step 2: Calculate final price after GST hike:
\[ \text{Final Price} = 1000 \times \left(1 + \frac{18}{100}\right) = 1000 \times 1.18 = Rs.1180 \]
Step 3: Calculate price increase due to GST hike:
\[ 1180 - 1120 = Rs.60 \]
Answer: The product price increases by Rs.60 due to the GST rate change from 12% to 18%, raising the final price from Rs.1120 to Rs.1180.
Step 1: Calculate percentage increase:
\[ \frac{52,500 - 50,000}{50,000} \times 100 = \frac{2,500}{50,000} \times 100 = 5\% \]
Step 2: Interpretation: A 5% rise in Sensex suggests positive investor sentiment and confidence in the economy or corporate earnings.
Answer: Sensex increased by 5%, indicating a bullish market trend.
Step 1: Calculate the increased FDI inflow:
\[ \text{New FDI} = 1,00,000 \times \left(1 + \frac{20}{100}\right) = 1,00,000 \times 1.20 = Rs.1,20,000 \text{ crore} \]
Step 2: Interpretation: A 20% increase in FDI inflows means more foreign capital is entering India, which can boost industrial growth, create jobs, and improve technology transfer.
Answer: FDI inflows rose to Rs.1,20,000 crore, positively impacting economic development and employment.
