Detailed Solution
Download Solution PDFमाना कि भिन्न x है।
व्युत्क्रम = 1/x
तब,
x + 3/x = 73/20
⇒ x2 + 3 = 73x/20
⇒ 20x2 – 73x + 60 = 0
⇒ x = {- (-73) + √ (5329 – 4800)}/40 या x = {- (-73) - √ (5329 – 4800)}/40
⇒ x = 96/40 = 12/5 या x = 50/40 = 5/4
∴ अभीष्ट भिन्न 5/4 या 12/5 है।Last updated on Jul 12, 2025
