If \(\frac{1}{x}\) ∶ \(\frac{1}{y}\) ∶ \(\frac{1}{z}\) = 1 : 3 : 2 , then x : y : z = ?
Answer & explanation
Correct answer: option 3
\(\frac{1}{x}\) ∶ \(\frac{1}{y}\) ∶ \(\frac{1}{z}\) = 1 : 3 : 2
⇒ x : y : z = \(\frac{1}{1}\) ∶ \(\frac{1}{3}\) ∶ \(\frac{1}{2}\)
⇒ x : y : z = \(\frac{6}{1}\) ∶ \(\frac{6}{3}\) ∶ \(\frac{6}{2}\)
(Multiplying with LCM)
⇒ x : y : z = 6 : 2 : 3
