Chapter Overview & Mathematical Foundations: Approximation

Class 7 Mathematics Guide

Mastering Approximation in Class 7 Mathematics requires a clear understanding of core mathematical definitions, standard algebraic or geometric formulas, deductive proofs, and computational algorithms.

In school term exams and competitive assessments (Olympiads, NTSE, and JEE Foundation), questions from Approximation assess calculation speed, accuracy with signs/units, and the ability to eliminate distractor options under timed conditions.

Core Moral & Key Takeaway:

Consistent formula revision combined with structured practice of solved numerical problems guarantees complete conceptual mastery and exam confidence.

Here is a sneak peek of the questions included in this test set. Test your preparation by viewing the answer and detailed explanation before starting the timed exam.

What is the concept of APPROXIMATION (আসন্নমান) and what mathematical symbol represents it?

আসন্নমান বলতে কী বোঝায় এবং এর গাণিতিক প্রতীক কোন্টি?

Approximation (अनुमोदन) की अवधारणा क्या है और कौन सा गणितीय प्रतीक इसका प्रतिनिधित्व करता है?

Rounding off a number to a desired degree of accuracy or nearest place value ; Symbol is ~ (or ≈)কোনো সংখ্যাকে নির্দিষ্ট যথার্থতা বা নিকটতম স্থানে রূপান্তর করা ; প্রতীক হলো ≈किसी संख्या को सटीकता की वांछित डिग्री या निकटतम स्थानीय मान तक पूर्णांकित करना; प्रतीक ~ (या ≈) है

Finding the reciprocal of a number ; Symbol is 1/xএকটি সংখ্যার পারস্পরিক সন্ধান করা; চিহ্ন হল 1/xकिसी संख्या का व्युत्क्रम ज्ञात करना; प्रतीक 1/x है

Multiplying a number by 100একটি সংখ্যাকে 100 দ্বারা গুণ করা হচ্ছেकिसी संख्या को 100 से गुणा करना

Squaring a numberএকটি সংখ্যা বর্গ করাकिसी संख्या का वर्ग निकालना

Correct Answer: Option A

Explanation:

Approximation represents rounding to n decimal places or significant figures, denoted by approx.

আনুমানিক বৃত্তাকার n দশমিক স্থান বা উল্লেখযোগ্য পরিসংখ্যান উপস্থাপন করে, যা আনুমানিক দ্বারা চিহ্নিত।

सन्निकटन एन दशमलव स्थानों या महत्वपूर्ण अंकों तक पूर्णांकन का प्रतिनिधित्व करता है, जिसे लगभग द्वारा दर्शाया जाता है।

What is the fundamental RULE FOR ROUNDING OFF to a given decimal place?

নির্দিষ্ট দশমিক স্থান পর্যন্ত আসন্নমান নির্ণয়ের নিয়ম কী?

किसी दिए गए दशमलव स्थान तक पूर्णांकित करने का मूल नियम क्या है?

If the next digit is 0, 1, 2, 3, 4 -> drop it (Round Down) ; If the next digit is 5, 6, 7, 8, 9 -> add 1 to the preceding digit (Round Up)পরবর্তী অঙ্কটি ০, ১, ২, ৩, ৪ হলে অপরিবর্তিত থাকে ; পরবর্তী অঙ্কটি ৫, ৬, ৭, ৮, ৯ হলে পূর্ববর্তী অঙ্কের সাথে ১ যোগ করতে হয়यदि अगला अंक 0, 1, 2, 3, 4 है -> इसे छोड़ें (राउंड डाउन); यदि अगला अंक 5, 6, 7, 8, 9 है -> पिछले अंक में 1 जोड़ें (राउंड अप)

How Chapter-Wise Online CBT Tests Build Winning Habits for Future Competitive Exams

Early practice in middle school builds the mental muscle, speed, and analytical discipline required to ace NTSE, Olympiads, JNVST, Sainik School, and Future Competitive Exams.

Competitive Edge

Real-Time Clock Awareness & Pacing

समय प्रबंधन एवं गति नियंत्रण

In school examinations, students write answers without active pacing. In national entrance tests, students have barely 45-60 seconds per MCQ. Practicing with a 20-minute timer instills instinctive time-budgeting and prevents last-minute exam panic.

Mastery of the Elimination Technique

विकल्प निष्कासन विधि में दक्षता

Top rankers in competitive exams rarely compute every problem blindly. They spot subtle traps, evaluate extreme values, and eliminate 2 out of 4 distractors within seconds. Our 4-option sets teach critical distractor analysis.

CBT Screen Stamina & Digital Comfort

कंप्यूटर आधारित परीक्षा का सहज अभ्यास

Almost all major national exams (CUET, JEE, NEET, SSC, Banking) are 100% computer-based. Students who only study on paper experience eye strain and navigation mistakes on exam day. Early CBT practice creates effortless digital fluency.

Immunity to Negative Marking

सटीकता और नकारात्मक अंकन से सुरक्षा

Careless errors—such as misreading "NOT" or "EXCEPT"—ruin thousands of competitive aspirations each year. Regular objective testing builds the habit of double-checking question keywords before locking answers.

Instant Diagnostic Feedback Loop

तत्काल त्रुटि निवारण एवं आत्म-मूल्यांकन

Traditional paper tests take weeks to grade, by which time the student has forgotten their thought process. TargetExams provides instant scorecards and step-by-step solutions while the conceptual puzzle is still fresh.
