Model Answer

Mathematical Fraction Solution:

  1. Equation: 4 1/2 + 3 1/6 + ? + 2 1/3 = 13 2/5
  2. Convert to improper fractions:
    (9/2) + (19/6) + ? + (7/3) = 67/5
  3. Sum of known components (LCM = 6):
    (27 + 19 + 14) / 6 = 60 / 6 = 10
  4. Calculate unknown: 10 + ? = 67/5 ⇒ ? = 67/5 - 10 = 17/5 = 3 2/5 (3.4)

Answer: The missing value is 3 2/5 (or 17/5).

हिंदी में प्रश्न एवं आदर्श उत्तर

निम्न समीकरण में प्रश्नवाचक चिन्ह किस मान द्वारा प्रतिस्थापित होगा ?
4 1/2 + 3 1/6 + ? + 2 1/3 = 13 2/5

हल:

  1. समीकरण: 4 1/2 + 3 1/6 + ? + 2 1/3 = 13 2/5
  2. भिन्न रूपों में बदलने पर:
    (9/2) + (19/6) + ? + (7/3) = 67/5
  3. ज्ञात पदों का योग (ल.स. = 6):
    (27 + 19 + 14) / 6 = 60 / 6 = 10
  4. 10 + ? = 67/5 = 13.4
    ? = (67/5) - 10 = (67 - 50) / 5 = 17 / 5 = 3 2/5 (या 3.4)

उत्तर: प्रश्नवाचक चिन्ह का मान 3 2/5 (17/5) होगा।
