A सीधे B के धनात्मक वर्गमूल के अनुक्रमानुपाती है।
A = 15 है, जब B = 27 और C = 2 है।
प्रयुक्त अवधारणा:
यदि P ∝ Q और P ∝ R, तब P ∝ QR और P = H × QR; (यहाँ, H एक स्थिरांक है)
गणना:
प्रश्नानुसार,
A ∝ \(\sqrt {B}\) और A ∝ 1/C3
इसलिए, A ∝ \(\frac {\sqrt B}{C^3}\)
⇒ A = k × \(\frac {\sqrt B}{C^3}\) ....(1) (यहाँ, k एक नियतांक है)
अब समीकरण (1) में A = 15, B = 27 और C = 2 रखने पर,
A = k × \(\frac {\sqrt B}{C^3}\)
⇒ 15 = k × \(\frac {\sqrt {27}}{2^3}\)
⇒ k = \(\frac {120}{3\sqrt {3}}\)
⇒ k = \(\frac {40}{\sqrt {3}}\)
अब जब A = 9 और C = 2 है,
A = k × \(\frac {\sqrt B}{C^3}\)
⇒ 9 = \(\frac {40}{\sqrt {3}}\) × \(\frac {\sqrt B}{2^3}\)
⇒ \(\sqrt {\frac {B}{3}}\) = 9/5
⇒ B/3 = 81/25
⇒ B = 243/25
∴ B का मान \(\frac{243}{25}\) है।
