Continuity and Differentiability — सांतत्य तथा अवकलनीयता

A function continuous at a if left = right = f(a). Chain, product, quotient, inverse trig derivatives, and Rolle/Lagrange as the book keeps them. Differentiable ⇒ continuous; converse false. A corner is the |x| story. You are on Continuity and Differentiability (MCQ test), page 1 of 1 — 8 questions in this filter. The MCQ test keeps four options visible and the correct letter folded. Use it as a 15-minute drill: one page, twenty items, no peeking. Search intent for class 12 mathematics mcq test and objective questions with answers is answered here with explanations, not a bare key. 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.

  • A. अंतिम उत्तर गढ़ना
  • B. ज्ञात-अज्ञात और मात्रक लिखना
  • C. केवल चित्र रंगना
  • D. फॉर्मूला बिना पढ़े रटना
View the correct answer

Correct option: B — ज्ञात-अज्ञात और मात्रक लिखना

NCERT numericals मात्रक और अज्ञात साफ चाहती हैं।

Q.58 MCQ Continuity and Differentiability

Continuity and Differentiability में गलत सर्वसमिका/सूत्र चुनें।

  • A. जाँच के लिए छोटी संख्या रखें
  • B. दोनों पक्ष बराबर होने चाहिए
  • C. किसी भी दो पद जोड़कर नया सूत्र बना लें
  • D. मात्रक दोनों पक्षों पर समान
View the correct answer

Correct option: C — किसी भी दो पद जोड़कर नया सूत्र बना लें

मनगढ़ंत सूत्र Class 12 पेपर काटते हैं।

Q.59 MCQ Continuity and Differentiability

Continuity and Differentiability अनुप्रयोग: 262 का 20% = ?

  • A. 242
  • B. 52
  • C. 282
  • D. 20
View the correct answer

Correct option: B — 52

262×20/100 = 52। प्रतिशत Comparing Quantities से पूरे गणित में चलता है।
