Core ConceptRead this first — the foundation of the topic
Types of Inflation
• Demand-Pull: Too much money chasing few goods
• Cost-Push: Production costs increase, pushing prices up
• Built-in: Expectations of future inflation drive current price rises
Inflation Formula: Inflation Rate = [(Current Year Price - Previous Year Price) / Previous Year Price] × 100
GDP vs GNP - Key Differences
GDP (Gross Domestic Product) = Total value of goods and services produced WITHIN a country's borders, regardless of who produces them.
GNP (Gross National Product) = Total value of goods and services produced BY a country's citizens, regardless of where they produce them
Simple Memory Trick
GDP = Domestic (within borders), GNP = National (by citizens)
GDP Formula: GDP = C + I + G + (X - M)
Where: C = Consumption, I = Investment, G = Government Spending, X = Exports, M = Imports

Exam PatternsWhat examiners ask — read before attempting PYQs
**
SSC CGL typically asks:
1. Current inflation rates and WPI/CPI differences
2. GDP growth rates of India
3. Comparison between nominal and real GDP
4.
Types of inflation with examples
5. GDP vs GNP numerical problems
Shortcut for GDP/GNP Problems
Quick Formula: GNP = GDP + Net Factor Income from Abroad
If Indians earn more abroad than foreigners earn in India: GNP > GDP
If foreigners earn more in India: GDP > GNP
**
Worked ExampleSolve this step-by-step before moving on
1
Step 1
Identify values - Previous year = 20, Current year = 24
2
Step 2
Apply formula = [(24-20)/20] × 100
3
Step 3
Calculate = (4/20) × 100 = 20%
Answer: Inflation rate is 20%
Worked Example 2: GDP vs GNP
Problem: India's GDP = Rs. 100 lakh crore. Indians abroad earn Rs. 5 lakh crore. Foreigners in India earn Rs. 3 lakh crore. Find GNP.
1
Step 1
Calculate Net Factor Income = Income by Indians abroad - Income by foreigners in India
2
Step 2
Net Factor Income = 5 - 3 = Rs. 2 lakh crore
3
Step 3
Apply GNP formula = GDP + Net Factor Income = 100 + 2 = Rs. 102 lakh crore
Answer: India's GNP = Rs. 102 lakh crore
Exam Shortcut: WPI vs CPI
WPI (Wholesale Price Index) = Inflation at producer level, includes raw materials
CPI (Consumer Price Index) = Inflation at consumer level, includes services
Trick: WPI = Wholesale = Producer, CPI = Consumer = Retail

Exam TrapsCommon mistakes students make — avoid these
Students confuse Real GDP with Nominal GDP:
• Nominal GDP = Current year prices (includes inflation effect)
• Real GDP = Base year prices (inflation removed)
Real GDP gives true economic growth. Always check if the question asks for real or nominal values.
Current Affairs Connection**
India targets 4% inflation rate. RBI uses CPI for monetary policy decisions.
Current GDP growth target is around 6-7%. These figures change frequently, so stay updated with economic surveys and budget announcements.
Key Points to Remember
Inflation = General rise in prices over time, reduces purchasing power of money
GDP measures production within country borders, GNP measures production by country's citizens
