What case-based questions really are, why they’re not as scary as they look, and a step-by-step method to approach any of them.
If case study questions are the part of the Class 10 Maths paper you’re dreading, here’s the reassurance you need: they’re one of the most learnable parts of the whole exam. Case study questions in Class 10 Maths aren’t testing harder maths — they’re testing familiar maths wrapped in a real-world situation. Once you have a clear method for unpacking that situation, they stop being scary and start being some of the most predictable marks on the paper. This guide gives you exactly that method.
What are case study questions in Class 10 Maths?
A case study question (also called a case-based or competency-based question) gives you a short real-world scenario — a situation, often with some data, a table, or a diagram — followed by a few connected sub-questions based on it. Instead of asking “solve this equation,” it might describe a shopkeeper, a cricket match, or a garden, and ask you to apply maths to that situation.
They appear in Section E of your paper: three case-study questions, each worth 4 marks — 12 marks in total. Each one typically has two or three sub-questions that build on the same scenario. For where they sit in the full paper, see the exam pattern guide.
Why CBSE asks case-based questions
Understanding why these exist takes away most of the fear. CBSE introduced case-based questions to test whether you can apply maths, not just perform it in the abstract. Real life doesn’t hand you a tidy equation — it hands you a situation, and expects you to spot the maths inside it. That’s a genuinely useful skill, and it’s what these questions reward.
The key insight: the maths itself is from the same syllabus you already know. A case study won’t ask you anything beyond your chapters. It just dresses a familiar concept — a bit of trigonometry, an arithmetic progression, some coordinate geometry — in a real-world story. Your job is to see through the story to the maths underneath.
The structure of a case study question
Each case study has two parts: the scenario (the situation and its data) and the sub-questions (usually two or three, building on each other). The earlier sub-questions are often simpler and set up the later ones. Because they’re worth 4 marks and sit in the subjective part of the paper, you’re expected to show your working — method marks apply here just as they do elsewhere.
A step-by-step method to solve any case study
This is the heart of it. Use the same five steps every single time, and case studies become routine:
1. Read the whole scenario first — before looking at the questions. This is the step most students skip, and it’s the most important. Read the entire situation calmly and get a clear picture of what’s happening before you even glance at the sub-questions. Rushing straight to the questions is the number-one cause of case-study mistakes.
2. Spot the maths concept. Ask yourself: which chapter is this really about? A scenario about a ladder against a wall is trigonometry. A savings-that-grow-each-month story is arithmetic progressions. Once you name the concept, you know which tools to reach for.
3. Extract the given data. Pull out the numbers and facts the scenario gives you, and note what each represents. Writing them down clearly turns a wordy paragraph into a normal maths problem.
4. Solve the sub-questions in order. They’re usually designed to build on each other — the first is often simpler and sets up the later ones. Answer them in sequence, showing your working (these are subjective questions, so method marks count).
5. Check your answer against the situation. A quick sanity check: does your answer make sense in the real-world context? If a question asks for the height of a building and you get 2 metres, something’s gone wrong. This catch-it-early habit saves marks.
Seeing the method in action
Here’s an illustrative example (not a real exam question — just to show the method working):
“A gardener is planting a triangular flower bed. She stands 15 metres from the base of a tall tree and measures the angle to the top of the tree as 30°. She wants to work out the height of the tree to plan the shade.”
Watch the method do the work:
- Read it all: the situation is about a tree, a distance, and an angle — we want a height.
- Spot the concept: an angle, a horizontal distance, and a height — this is trigonometry (heights and distances).
- Extract the data: distance from tree = 15 m, angle of elevation = 30°, height = unknown.
- Solve: height and the known distance relate through tan(30°), so height = 15 × tan(30°) — a familiar calculation from your trigonometry chapter.
- Check: the answer comes out to a sensible tree height, so it makes sense in context.
Notice what happened: the “scary” case study became an ordinary trigonometry question the moment we applied the method. That’s the whole trick — the method turns a story back into maths you already know.
Common mistakes on case-study questions
Avoid these and you’re most of the way there:
- Jumping to the sub-questions without reading the full scenario — you miss context and given data.
- Missing data hidden in the wording — case studies often tuck a key number into a sentence. Read carefully and note everything.
- Panicking at the length — more text doesn’t mean harder maths. Stay calm; the maths is from your syllabus.
- Not showing working — these are 4-mark subjective questions; method marks matter, so write your steps.
- Skipping the sanity check — a quick “does this make sense?” catches errors before they cost you.
How to practise case studies
Case studies are a skill, and skills come from repetition. The good news is that the translation ability — reading a scenario and spotting the maths — gets noticeably easier with practice. Work through varied case-based questions across different chapters, apply the five-step method every time, and you’ll soon find the “wrapping” barely slows you down.
This is exactly where focused practice pays off. examfront gives you case-study practice across every chapter, and helps you see where your translation is slipping — whether you’re missing given data, picking the wrong concept, or rushing the read. Since case studies test a skill you build by doing, targeted practice is the fastest way to turn these 12 marks from a worry into a strength. Practise case studies with examfront and make Section E one of your most confident sections.

Frequently asked questions
What are case study questions in Class 10 Maths? They’re questions that present a real-world scenario — a situation with some data — followed by a few connected sub-questions that ask you to apply maths from your syllabus to that situation. They appear in Section E, worth 4 marks each.
How many case study questions are in the Class 10 Maths paper? Three, in Section E, each worth 4 marks — 12 marks in total. Each usually has two or three sub-questions based on the same scenario.
Are case study questions hard? They feel harder because of the reading involved, but the maths is from the same syllabus you already study. With a clear method — read the scenario, spot the concept, extract the data, solve, check — they become very manageable.
How do I get better at case-based questions? Practise them regularly using a fixed method, across different chapters. The skill being tested is translating a real situation into maths, and that gets much easier with repetition.
