AD / AS
AD curve above 45° line at full employment level; gap between AD and AS at full employment = inflationary gap
4-6
36
Deficient Demand (Deflationary Gap)
Income / Output (Y)
AD / AS
AD curve below 45° line at full employment level; gap between AS and AD at full employment = deflationary gap
4-6
37
Investment Multiplier
Income / Output (Y)
AD
Show two AD curves (before and after increase in investment ΔI); increase in income ΔY is multiple of ΔI; K = ΔY/ΔI = 1/(1-MPC)
4-6
Money, Banking, and Government Budget (Diagrams 38-40)
#
Diagram Name
Key Elements to Draw
Typical Marks
38
Money Supply and Demand (Equilibrium Interest Rate)
X-axis: Quantity of Money, Y-axis: Interest Rate. Money supply (MS): vertical line (fixed by RBI). Money demand (MD): downward sloping. Intersection = equilibrium interest rate
3-4
39
Credit Creation by Commercial Banks
Flowchart: Initial deposit → LRR kept as reserve → Remaining lent out → Re-deposited → LRR kept → lent out → continues. Total credit = Initial Deposit × (1/LRR)

40
Government Budget Components
Flowchart/Tree diagram: Budget → Revenue Budget (Revenue Receipts + Revenue Expenditure) + Capital Budget (Capital Receipts + Capital Expenditure). Show sub-items under each.
3
Foreign Exchange (Diagrams 41-42)

Key Elements to Draw
Typical Marks
41
Foreign Exchange Rate Determination
Quantity of Foreign Exchange (say $)
Exchange Rate (₹ per $)
Demand for $ (downward sloping — importers need $), Supply of $ (upward sloping — exporters supply $), intersection = equilibrium exchange rate
4
42
Change in Exchange Rate (Depreciation/Appreciation)
Quantity of $
Exchange Rate (₹ per $)
Shift in demand or supply curve; rightward shift in demand = depreciation of ₹ (rate rises); rightward shift in supply = appreciation of ₹ (rate falls)

Common Diagram Mistakes to Avoid
Mistake
Why It Costs Marks
Not labelling axes
Examiners cannot give marks if axes are unlabelled — even if the curve is correct
Drawing straight lines instead of curves
Cost curves (AC, MC), utility curves (TU, MU), and IC curves should be smooth curves, not straight lines
Not marking equilibrium point clearly
Always label the equilibrium point as E or E₁, and draw dashed lines to both axes
Forgetting to show direction of shift
When showing a shift (demand increase, supply decrease), use arrows on the curve and label the new curve
Drawing MR above AR in imperfect competition
MR is always below AR when AR is downward sloping — never above
Confusing movement vs shift
Movement = along the curve (price change). Shift = entire curve moves (non-price factor change)
Not showing the 45° line in AD-AS diagrams
The 45° line represents Y = AD and is essential for showing equilibrium in Keynesian cross
Mixing up inflationary and deflationary gaps
Inflationary: AD > AS at full employment. Deflationary: AD < AS at full employment
Diagram Drawing Checklist (Use Before Every Practice)
Check
Done?
X-axis labelled with correct variable name
Y-axis labelled with correct variable name
Origin marked as "O"
Curves labelled (D, S, MC, AC, AR, MR, etc.)
Equilibrium point marked (E)
Dashed lines from equilibrium to both axes
Equilibrium values labelled (P₀, Q₀, Y₀)
If shift: new curve labelled (D₂, S₂, AD₂)
If shift: new equilibrium marked (E₁ or E₂)
Arrow showing direction of change
Frequently Asked Questions
Q1. How many diagram-based questions come in the Class 12 Economics board exam?
Typically 5-8 questions require diagrams. These include 1-mark MCQs (identify the correct curve), 3-mark questions (draw and explain), and 6-mark questions (draw diagram and use it to explain a concept). Total diagram-related marks: 15-25 out of 80.
Q2. Will I lose marks if my diagram is not perfectly drawn?
Minor imperfections are fine — examiners do not expect computer-drawn graphs. What matters is: correct shape, correct axis labels, correct curve labels, and correct equilibrium points. A rough but correctly labelled diagram gets full marks.
Q3. Which diagrams are asked most often?
Market equilibrium (D-S), cost curves (AC-MC relationship), profit maximisation under different market forms, AD-AS equilibrium with inflationary/deflationary gap, and foreign exchange rate determination are the top 5 most repeated diagram questions.
Q4. Should I draw diagrams even when the question does not ask for one?
If the question says "explain with the help of a diagram," you must draw one. Even when not explicitly asked, adding a relevant diagram in 4-mark and 6-mark answers often earns an extra mark for presentation.
Q5. Are the diagrams the same for Indian Economic Development (Part B)?
Indian Economic Development (Part B) has very few diagrams — mostly data tables and flowcharts. The diagrams in this list cover Part A (Micro and Macro), which is where 90 percent of diagram marks come from.
Q6. How long should I spend drawing a diagram in the exam?
A well-drawn diagram with labels should take 2-3 minutes. Do not spend more than 5 minutes on any single diagram. Draw the basic structure first, add labels, then write the explanation.
