Class 10 Mathematics — Real Numbers Important Questions with Answers (Long answers)
Class 10 Mathematics is still the CBSE board paper that rewards NCERT exercise lines more than imported entrance tricks. Real numbers (Euclid, fundamental theorem), quadratic formula, similar triangles, trigonometry identities, circles and surface area are the high-search clusters. This hub writes 150+ important questions with a hidden key so you can run a 20-question mock without scrolling a 40-screen PDF. No invented board date — only rationalized 2023–26 chapter names.
Euclid’s division lemma and the Fundamental Theorem of Arithmetic are the two engines. HCF × LCM = product for two positives. Terminating versus non-terminating recurring decimals follow the prime factors of the denominator after the fraction is in lowest terms. Irrationals such as √2 stay irrational in the usual school proofs. Class 10 no longer dwells on the old “revisiting irrationality” extras that some reprints dropped — these questions follow the slim chapter. You are on Real Numbers (Long answers), page 1 of 1 — 2 questions in this filter. Long answers model a five-mark write-up: definition, reason, one diagram or equation idea, and a closing line. Do not copy the whole block in the exam; steal the order. This view is for the night before a unit test. Phone layout: chapter chips scroll sideways, answers stay inside a tap, and the next page is a numbered link so Google and students both get a short URL. Updated for 2026 classroom practice on the rationalized NCERT.

Euclid’s division lemma and the Fundamental Theorem of Arithmetic are the two engines. HCF × LCM = product for two positives. Terminating versus non-terminating recurring decimals follow the prime factors of the denominator after the fraction is in lowest terms. Irrationals such as √2 stay irrational in the usual school proofs. Class 10 no longer dwells on the old “revisiting irrationality” extras that some reprints dropped — these questions follow the slim chapter.
चार बिंदु: (1) NCERT परिभाषा/सूत्र/घटना। (2) एक उदाहरण या आरेख-विचार। (3) एक तुलना या कारण। (4) एक साधारण संख्यात्मक या उद्धरण यदि पाठ माँगता है।
निष्कर्ष: उत्तर अध्याय-सत्य रखें — बोर्ड की डेटशीट यहाँ नहीं गढ़ी गई।
