Proportion Solution:

  • Given terms are in continuous proportion: 2 : x :: x : 8
  • Product of Extremes = Product of Means:
    x × x = 2 × 8
    x² = 16 ⇒ x = 4

Answer: The value of x is 4.

हिंदी में प्रश्न एवं आदर्श उत्तर

यदि संख्याएँ 2, x, x, 8 समानुपात में हैं, तो x ज्ञात कीजिए।

हल:

  • दी गई संख्याएँ 2, x, x, 8 समानुपात में हैं: 2 : x :: x : 8
  • समानुपात का नियम: बाह्य पदों का गुणनफल = मध्य पदों का गुणनफल
    x × x = 2 × 8
    x² = 16 ⇒ x = √16 = 4 (धनात्मक मान)
