एक सरल रेखा, जो एक अचर बिन्दु \((2,3)\) से होकर जाती है, निर्देशांक अक्षों को दो विभिन्न बिन्दुओं \(P\) तथा \(Q\) पर प्रतिच्छेद करती है। यदि \(O\) मूल बिन्दु है तथा आयत \(O P R Q\) को पूरा किया जाता है तो \(R\) का बिन्दुपथ है

  1. A \(2x + 3y = xy\)
  2. B \(3x + 2y = xy\)
  3. C \(3x + 2y = 6xy\)
  4. D \(3x + 2y = 6\).
Verified Solution

Answer & Solution

Correct Answer

(B) \(3x + 2y = xy\)

Step-by-step Solution

Detailed explanation

Equation of \(PQ\) is \(\frac{x}{h} + \frac{y}{k} = 1\,\,\,\,\,\,\,......\left( 1 \right)\) Since, \((1)\) passes through the fixed point \((2,3)\) Then, \(\frac{2}{h} + \frac{3}{k} = 1\,\) Then, the locus of \(R\) is \(\frac{2}{x} + \frac{3}{y} = 1\) or \(3x + 2y = xy\).
