ICSE Class 10 Solutions: Step-by-Step Board Study Guide
What are ICSE Class 10 Solutions?
ICSE Class 10 Solutions are step-by-step answers to textbook exercises, specimen-style questions, previous year questions and competency focused practice for students following the CISCE Class 10 course. They should be used to check method, keywords, units and answer format after you first attempt the question yourself.
This page replaces the old thin index with a subject-wise study guide, solved examples and teacher-style notes on how to use solutions without copying. It does not include date sheets, result dates or admit-card information because those details change every year.
Concept Snapshot: A solution is a route map
A worked answer is like a route map. If you only copy the route, you may reach one answer, but you will not know how to travel alone in the exam hall. If you try the question, mark the stuck step and then compare it with the solution, the method becomes yours.
A useful Class 10 solution should show the given data, the rule or formula, the working steps, and the final answer with the correct unit or subject keyword.
How to use Class 10 solutions correctly
Use solutions as a checking tool, not as the first step. In Mathematics and Physics, the method matters as much as the result. In Chemistry, a balanced equation or correct observation can decide the answer. In Biology, History, Civics and Geography, correct terms and point-wise structure matter. In Computer Applications, syntax and logic must both be correct.
- Attempt first: write your own answer before opening the solution.
- Compare the method: check the formula, theorem, law, equation, diagram label or Java statement used.
- Correct the weak step: rewrite only the step that failed, then solve the question again later.
- Track errors: mark each mistake as formula, unit, keyword, diagram, map, syntax or skipped-step error.

Worked examples from Class 10 topics
The examples below are original practice examples written to show how working should be displayed. They are not copied from a textbook exercise.
Worked Example 1: Recurring deposit in Mathematics
Question: A student deposits ₹500 every month in a recurring deposit account for 12 months at 6% per annum. Find the interest and maturity value.
Formula: I=\frac{P\times n(n+1)\times r}{2\times12\times100}
Here, P=500, n=12, r=6.
I=\frac{500\times12\times13\times6}{2400}=195Total deposit =500\times12=6000.
Maturity value =6000+195=6195.
Final answer: Interest = ₹195; maturity value = ₹6,195.
Worked Example 2: Series circuit in Physics
Question: Resistors of 2\Omega and 3\Omega are connected in series across a 10 V battery. Find total resistance, current and potential difference across the 3\Omega resistor.
In series, R=R_1+R_2=2+3=5\Omega.
Using Ohm’s law, I=\frac{V}{R}=\frac{10}{5}=2A.
Potential difference across 3\Omega: V=IR=2\times3=6V.
Final answer: Total resistance = 5\Omega, current = 2A, potential difference = 6V.
Worked Example 3: Mass calculation in Chemistry
Question: Find the mass of carbon dioxide formed when 5.6 g of carbon monoxide burns completely in oxygen. Use C = 12 and O = 16.
Balanced equation: 2CO+O_2\rightarrow2CO_2. The mole ratio of CO to CO_2 is 1 : 1.
Molar mass of CO=12+16=28g\,mol^{-1}.
Moles of CO=\frac{5.6}{28}=0.2mol. Therefore, moles of CO_2=0.2mol.
Molar mass of CO_2=12+16+16=44g\,mol^{-1}.
Mass of CO_2=0.2\times44=8.8g.
Final answer: 8.8 g of carbon dioxide is formed.
Board preparation method using ICSE Class 10 Solutions
Use the cycle learn → attempt → check → correct → retry. For Maths, write the formula or theorem before substitution. For Physics, write units with every numerical answer. For Chemistry, balance equations before using mole ratios. For Biology, use exact terms and labelled diagrams. For History, Civics and Geography, write concise points instead of vague paragraphs. For Computer Applications, trace code before writing the final output.
Examiner’s mindset for Class 10 answers
Marking schemes vary by subject and year, so do not assume a fixed mark split unless your teacher provides one. Still, examiners can award credit more easily when the method is visible.
- Numericals: show formula, substitution, calculation and unit.
- Theory: begin with the correct term, then explain it.
- Diagrams and maps: labels must be correct and placed clearly.
- Programs: syntax, logic and output all matter.
Common mistakes students make
- Copying final answers: rewrite the method in your own notebook.
- Dropping units: check V, A, \Omega, g, mol, cm and m where required.
- Using unbalanced equations: balance first, then calculate.
- Missing keywords: use the exact scientific, historical or geographical term.
- Not tracing code: test loop values and conditions before writing output.
Official sources to check alongside solutions
Use the CISCE official website for regulations, syllabus documents and specimen papers. For overlapping concepts in science and mathematics, NCERT can be used as a standard reference, but your final preparation should follow the ICSE syllabus and the textbook used by your school.
Frequently Asked Questions
How should I use ICSE Class 10 Solutions without copying answers?
Attempt the question first, then compare your method with the ICSE Class 10 Solutions. Rewrite the step where your answer went wrong, because the correction is what improves exam readiness.
Are ICSE Class 10 Solutions enough for board preparation?
ICSE Class 10 Solutions are useful for checking method and answer structure, but they should be used with the official CISCE syllabus, textbook exercises, school notes, practical work and timed practice papers.
Which subjects need step-by-step working in ICSE Class 10?
Mathematics, Physics, Chemistry numericals and many Computer Applications programs need step-by-step working. In theory subjects, the steps become definition, key term, explanation, example and conclusion.
How do competency focused questions differ from regular textbook questions?
Competency focused questions test whether you can apply a concept to a new situation. A textbook question may ask for a direct formula, while a competency question may hide the same formula inside a case, graph, table or real-life situation.
Should I solve previous year question papers before finishing the syllabus?
Use previous year question papers chapter-wise after you finish a topic. Full timed papers should be attempted only after most of the syllabus has been revised, otherwise the paper becomes a guessing exercise.
