NCERT MCQ Solutions for Class 8 Mathematics

Practicing Multiple Choice Questions for Class 8 Maths is an effective way to strengthen problem-solving skills and improve accuracy. MCQs cover various concepts like algebra, geometry and data handling, helping students test their understanding efficiently. Since MCQs provide multiple answer choices, students must carefully analyze each option before selecting the correct one. For example, a typical MCQ might be: “What is the square root of 144?” A) 10 B) 12 C) 14 D) 16. Here, the student needs to recall square root concepts and eliminate incorrect options. Regular practice with such MCQs enhances conceptual clarity and boosts confidence. Moreover, time-bound MCQ quizzes prepare students for exams by improving speed and accuracy, making problem-solving more effective.

To master MCQs in Class 8 Maths, students should use strategies like elimination, estimation and unit checking. The elimination method helps in ruling out incorrect answers, while estimation aids in quickly arriving at approximate solutions. Consider the following MCQ: “If x = 5, what is the value of 2x + 3?” A) 8 B) 10 C) 12 D) 13. By substituting x = 5, students get 2(5) + 3 = 13, making option D the correct answer. Another approach is using unit checking for questions involving measurements or conversions. For instance, “How many millimeters are there in 5 centimeters?” A) 50 B) 500 C) 5 D) 5000. Knowing that 1 cm = 10 mm makes the correct answer A) 50. These strategies help in quick and accurate MCQ-solving.

Solving MCQs regularly not only enhances speed but also strengthens retention of mathematical concepts. Since exams often include objective-type questions, practicing MCQs improves exam performance and reduces anxiety. An example MCQ could be: “What is the value of (3² + 4²)?” A) 9 B) 16 C) 25 D) 7. Applying the squares, we get 9 + 16 = 25, making option C correct. MCQs often focus on conceptual understanding rather than lengthy calculations, which makes learning more engaging. Another question like “Which of the following numbers is divisible by 9?” A) 243 B) 245 C) 248 D) 250 encourages students to recall divisibility rules, leading to faster problem-solving. Thus, consistent MCQ practice builds strong mathematical reasoning and better exam preparedness.

When practicing Multiple Choice Questions in Class 8 Mathematics, it is crucial to understand the underlying concept rather than just memorizing answers. Every question is designed to test logical reasoning and conceptual clarity. For instance, an MCQ like “What is the value of (15 ÷ 3) + (4 × 2)?” A) 10 B) 11 C) 12 D) 13 requires knowledge of BODMAS (Bracket, Order, Division, Multiplication, Addition, Subtraction). Solving step-by-step, 15 ÷ 3 = 5 and 4 × 2 = 8, then 5 + 8 = 13, making option D correct. Without understanding BODMAS, students might arrive at incorrect answers. Practicing MCQs with a focus on concepts strengthens foundational knowledge and prepares students for higher-level problem-solving.

Time management is essential when solving MCQs in Class 8 Mathematics, as exams often have limited time for numerous questions. Quick calculations and elimination methods can help in selecting the correct answer faster. Consider the MCQ: “Which of the following fractions is equivalent to 3/4?” A) 6/8 B) 5/9 C) 2/5 D) 9/12. By simplifying 6/8 = 3/4, we confirm that option A is correct. Instead of solving each option fully, recognizing equivalent fractions quickly saves time. Another useful trick is approximation, as in “What is the approximate value of 3.1415 × 2?” A) 5 B) 6 C) 7 D) 8, where estimating π ≈ 3.14 makes 3.14 × 2 ≈ 6.28, pointing to option B. Such time-saving techniques improve accuracy and speed.

Many students make mistakes in MCQs due to careless errors, misreading questions or overlooking negative signs. Careful reading is essential to avoid confusion. For example, “If -7 + x = 5, what is x?” A) 12 B) -12 C) -2 D) 2 requires solving -7 + x = 5 by adding 7 to both sides, giving x = 12, making option A correct. A common mistake is missing the negative sign, leading to wrong choices.

Another tricky MCQ is “Which of the following numbers is prime?” A) 25 B) 27 C) 31 D) 33, where students might mistakenly choose composite numbers instead of the correct prime number, which is option C (31). By carefully reviewing answers before selection, students can avoid such errors and improve accuracy.
