Why Correct: Inflation is defined as a sustained increase in the general price level of goods and services over a period. A one-time rise does not qualify because inflation implies continuity.
Distractor Analysis: A one-time price level rise is a price shock, not inflation. Increasing profits in production is not a macroeconomic definition of inflation. Increase in deficit financing is a potential cause of inflation, not its definition.
Takeaway: Inflation is a persistent upward movement; transitory spikes are not considered inflation.

Why Correct: Inflation in India has historically been single-digit and positive, typically ranging between 2% and 6% in recent years.
Distractor Analysis: Double-digit inflation (above 10%) occurred in India in the early 2010s but is not the current norm. Negative inflation (deflation) is rare in India. Zero inflation is not a characteristic of India's economy.
Takeaway: India's inflation target under the RBI is 4% with a 2-6% band, so single-digit positive inflation is the normal range.

Why Correct: Fixed income group is worst affected by inflation because their nominal income remains constant while purchasing power erodes as prices rise.
Distractor Analysis: Traders and merchants often benefit from inflation as they can increase prices. The investor class may benefit through asset price increases and inflation-indexed returns. Self-employed group can adjust their prices or income to keep pace with inflation.
Takeaway: Inflation acts as a regressive tax on fixed-income earners such as pensioners and salaried employees with stagnant wages.

Why Correct: The Wholesale Price Index (WPI) in India used 1990-91 as its base year from 1993-94 until the 2004-05 base year was adopted in 2009.
Distractor Analysis: 1991-92 and 1992-93 were never base years for the WPI; the index has used base years such as 1961-62, 1970-71, 1981-82, 1993-94, and 2004-05. 1993-94 served as a base year for the WPI from 2000-01 to 2009, but it was not the base year in the question's context, which refers to the earlier series.
Takeaway: The WPI base year was revised to 2011-12 in 2017, and the government plans to shift to 2022-23 as the new base year for the WPI series.

Why Correct: Dearness Allowance (DA) for urban salaried workers and government employees in India is determined based on the Consumer Price Index for Urban Non-Manual Employees (CPI-UNME).
Distractor Analysis: Wholesale Price Index (WPI) measures price changes at wholesale level, not used for DA. Consumer Price Index (CPI) is a general term; the specific index matters. CPI for Agricultural Labourers (CPI-AL) is used for DA for farm workers, not urban employees.
Takeaway: DA revisions aim to offset inflation; the specific CPI index used depends on the employee category.

Why Correct: Debtors benefit from inflation because the real value of their debt decreases as the purchasing power of money falls.
Distractor Analysis: Creditors lose from inflation as the money repaid has lower real value. Wage-earners suffer if wages do not keep pace with rising prices. Salaried classes similarly lose purchasing power unless salaries are indexed to inflation.
Takeaway: Inflation redistributes wealth from creditors to debtors and from fixed-income groups to variable-income groups.

Why Correct: Price stability emerges when aggregate supply and aggregate demand move in tandem. Raising production shifts the supply curve rightward, easing upward pressure on prices, while tightening the money supply curbs demand-pull inflation by reducing purchasing power. Together these two levers address both sides of the price equation, making them the effective stabilization tools.
Distractor Analysis: Examining the statements: increasing production directly expands real output, which lowers unit costs and relieves supply bottlenecks. Controlling the supply of money, typically through central bank instruments like repo rate changes or open market operations, reduces excess liquidity that fuels demand-pull inflation. Devaluation, by contrast, raises the domestic price of imported goods and makes exports cheaper, which can worsen imported inflation rather than stabilize prices.
Takeaway: The Reserve Bank of India primarily uses the repo rate and cash reserve ratio to manage money supply, while the government's production-side measures include agricultural output boosts and industrial capacity expansion; both arms together form the standard anti-inflation policy mix.
