Same pie, same base. Compare the percents, skip the rupees.

⚡ The 20-second answer
Each slice is a share of one fixed total. Amount = share% × total; total = amount ÷ share%. Within one pie, compare percents directly: the total cancels. The trap: slices from two pies can't be compared without both totals.

Tara's maths: A pie never grows a slice for free. Every slice is a share of the same ₹1,20,000, and the shares add to 100%. Here 1% = ₹1,200, so food's extra 5 points cost ₹6,000, and Aarav's DJ drops from 30% to 25%.
What does a pie chart actually tell you?
A pie chart answers one question: out of the whole, how much went where? It never says how big the whole is. A tiny pie and a giant pie look identical if the split matches.

📌 Percent and degrees are the same pie
360° is 100%, so 1% = 3.6° and 10% = 36°. Degrees ÷ 3.6 = percent: 90° is 25%, 72° is 20%.

How do you solve pie chart percentage questions step by step?
✍️ Worked exampleWarm-up⏱ 30 sec
Meher's monthly allowance
Meher gets ₹6,000 a month: food 30%, transport 15%, phone 10%, books 20%, fun 15%, savings 10%. How much more goes on food than on her phone?
1
Slow route: food = 30% of 6,000 = ₹1,800; phone = 10% of 6,000 = ₹600.
2
Difference = 1,800 − 600 = ₹1,200.
Answer: ₹1,200
⚡ The exam-hall shortcut
Work in percents: the gap is 20 points, and 1% = ₹60, so ₹1,200. One multiplication, not three.
✍️ Worked exampleCLAT level⏱ 50 sec
The society budget in degrees
A society's budget in degrees: workshops 126°, travel 90°, refreshments 72°, merchandise 45°, miscellaneous 27°. Refreshments cost ₹28,800. Find the total and the workshops amount.
1
Check: 126 + 90 + 72 + 45 + 27 = 360°.
2
Refreshments: 72 ÷ 3.6 = 20%, so total = 28,800 ÷ 0.20 = ₹1,44,000.
3
Workshops: 126 ÷ 3.6 = 35%, and 35% of 1,44,000 = ₹50,400.
Answer: Total ₹1,44,000; workshops ₹50,400
⚡ The exam-hall shortcut
Degrees are already a ratio: 126 ÷ 72 = 1.75, so workshops = 28,800 × 1.75 = ₹50,400.
✍️ Worked exampleCLAT level⏱ 60 sec
The family budget and the wrong base
Rohan's family income: rent 22%, food 28%, EMI 12%, education 18%, others 8%, savings 12%. Savings = ₹9,600. Find (a) the income, (b) the expenditure, (c) food as a percent of expenditure.
1
(a) Income = 9,600 ÷ 0.12 = ₹80,000.
2
(b) Expenditure = 100 − 12 = 88% of income = ₹70,400.
3
(c) Food = ₹22,400, and 22,400 ÷ 70,400 × 100 = 31.82%. New base, new percent.
Answer: (a) ₹80,000 (b) ₹70,400 (c) about 31.8%
⚡ The exam-hall shortcut
(c) needs no rupees: 28 ÷ 88 = 7/22 ≈ 31.8%, not 28%.
⚠️ % of income or % of spending?
The pie is usually drawn on income. If a question says 'of expenditure' and savings is a slice, the base shrinks to (100 − savings)%. Also check what income contains: in CLAT 2025, Mr Das's income was salary plus a 10% house rent allowance.
✍️ Worked exampleTricky⏱ 45 sec
Two companies, two pies
Company A spends ₹50 lakh, 20% on marketing. Company B spends ₹80 lakh, 15% on marketing. Who spends more on marketing, and by what percent?
1
A = 20% of 50 = ₹10 lakh. B = 15% of 80 = ₹12 lakh.
2
B spends more, by (12 − 10) ÷ 10 × 100 = 20%.
Answer: Company B, by 20%
⚡ The exam-hall shortcut
Two pies, two bases: percents are not comparable. Convert both to rupees.
📊 The data
Smaller slice, bigger spend
Company A: 20% of ₹50 lakh
₹10 lakh
Company B: 15% of ₹80 lakh
₹12 lakh
If the question hid B's total, the honest answer would be cannot be determined.
What is the fastest way to compare slices without calculating rupees?
Inside one pie, the total multiplies every slice equally, so it cancels. 'Is rent plus food more than education plus savings?' is just adding percents. Housing : education = 15 : 12 = 5 : 4, whatever the total.

12,880
8,400 ÷ 15 × 23 = 12,880
Savings 15% = ₹8,400, so food at 23% = ₹12,880. Set the last box to 100 to get the total (₹56,000).

How does CLAT hide a budget pie inside a paragraph?
CLAT now writes the pie as a sentence: 'he spends 25% on food, 18% on rent…'. Redraw it in ten seconds. In 2025, Mr Das earned ₹9,228 plus a 10% house rent allowance, so income = 9,228 × 1.1 = ₹10,150.80.

✓Slices that don't add to 100. The CLAT 2021 family budget adds to 105%. Add first.
✓Odd bases. CLAT 2021 called ₹56,000 the 'total amount spent', then asked for savings as 15% of it. Follow the paper's base.
✓% of a slice. '20% of the food budget went on snacks' is 20% of 25% = 5% of the whole.
✓Points vs percent. 30% vs 25%: 5 points, but 20% more.
✓A slice grows, income doesn't. Food (25%) up 10% takes 2.5 points from another slice.
How has CLAT asked budget and pie chart questions?
CLAT 2021 had a family budget and an age-group set; CLAT 2025 had Mr Das's budget.

Reveal answer + reasoning
Answer: A
Same pie, so ₹56,000 is a decoy. Others + clothing = 20 + 10 = 30%. Housing + education = 27%, food + transport = 33%, food + housing = 38%, housing + saving = 30%. Only 27% is lower. Answer A. Time: 25 seconds.
Why the others fail
B — 33% is higher than 30%.
C — 38% is higher still.
D — 30% equals 30%; 'higher than' needs strictly greater.

📝 Asked in CLAT 2025· Q117Comparing budget heads
Mr. Das… total monthly income includes a salary of Rs. 9228/- and a 10% house rent allowance… he spends 25% on food expenses, 18% on paying the house-rent, 9% on entertainment, 23% on the education of his child, 13% on medical expenses, and he saves 12%…
Which of the following is true regarding the home budget of Mr. Das?
AThe total amount spent on house-rent, entertainment and education is greater than the total amount spent on food expenses, medical expenses and savings
BThe total amount spent on entertainment, medical expenses and education is equal to the total amount spent on house-rent, food expenses and savings
CThe total amount spent on savings, medical expenses and education is less than the total amount spent on house-rent, food expenses and entertainment
DNone of the above
Reveal answer + reasoning
Answer: C
Don't compute the income. C: savings + medical + education = 12 + 13 + 23 = 48%; rent + food + entertainment = 18 + 25 + 9 = 52%. 48 is less than 52. Answer C. Time: 40 seconds, mostly reading.
Why the others fail
A — 18 + 9 + 23 = 50% and 25 + 13 + 12 = 50%. Equal, not greater.
B — 9 + 13 + 23 = 45% vs 18 + 25 + 12 = 55%. Not equal.
D — C is true, so 'None' fails.

Answer: C
Income = 9,228 × 1.1 = ₹10,150.80. Rent + savings = 30%, so 70% remains: 0.70 × 10,150.80 = ₹7,105.56 ≈ ₹7,106. Answer C. Time: 45 seconds. The options shuffle the same digits, so compute; don't eyeball.
Why the others fail
A — Digit swap of 7,106.
B — Too big: even 75% of income is ₹7,613.

Q1. In a pie chart, a slice measures 54°. What percent of the whole is it?
54 ÷ 3.6 = 15% (36° = 10%, 18° = 5%).
A hostel's mess budget is ₹2,40,000: vegetables 22%, grains 18%.
Q2. How much more is spent on vegetables than on grains?
Gap = 4 points; 1% = ₹2,400, so ₹9,600.
In a family pie, rent is 24% (₹14,400) and travel is 9%.
Q3. How much is spent on travel?
Ruler: 14,400 × 9/24 = ₹5,400. The total isn't needed.
Town X: budget ₹40 crore, 15% on health. Town Y: 20% on health, budget not given.
Q4. Which town spends more on health in rupees?
Two pies, one total missing: cannot be determined.
A student saves 15% of her income and spends 30% of her income on food.
Q5. Food is roughly what percent of her total spending?
Spending = 85% of income, so food = 30 ÷ 85 × 100 ≈ 35.3%. 30% uses the wrong base.
🎯 Pie charts and budgets in a nutshell
A pie shows shares of one total, never the size of the total.
Amount = share × total; total = amount ÷ share; slice B = slice A × B% ÷ A%.
Within one pie, compare and add the percents; multiply by the total once.
How do you calculate a percentage from a pie chart?
Divide the slice by the whole and multiply by 100. With rupees, that is slice ÷ total × 100. With degrees, divide by 3.6, because 360° is 100%, so a 72° slice is 20%. Once you have the percent, the amount is that percent of the total.
How do you find the total from a pie chart if only one value is given?
Divide the known amount by its share. If savings are 12% and equal ₹9,600, the total is 9,600 ÷ 0.12 = ₹80,000. Often you can skip the total: another slice equals the known amount times the ratio of the percents, so a 28% slice is 9,600 × 28/12 = ₹22,400.
Can you compare slices from two different pie charts?
Not by their percents. Each pie has its own total, so a 15% slice of a big pie can beat a 20% slice of a small one. Convert both slices to amounts using their own totals. If either total is missing, the CLAT answer is cannot be determined.
Are pie chart questions asked in CLAT?
Yes, usually as a paragraph rather than a drawn chart. CLAT 2021 had a family budget set and an age-group population set, and CLAT 2025 had Mr Das's home budget with six questions. Turn the paragraph into a quick table of shares and the questions become lookups.
