Consider the sound wave travelling in ideal gases of {\He}, {\CH}_4 and {\CO}_2. All the gases have the same ratio \frac{P}{\rho}, where P is the pressure and \rho is the density. The ratio of the speed of sound through the gases v_{ {\He}}: v_{ {\CH}_4}: v_{ {\CO}_2} is given by [4 Apr 2025 Shift 1]

Correct Answer is : √53:√43:√75

\sqrt{\frac{5}{3}}: \sqrt{\frac{4}{3}}: \sqrt{\frac{4}{3}}

\sqrt{\frac{5}{3}}: \sqrt{\frac{4}{3}}: \sqrt{\frac{7}{5}}

\sqrt{\frac{4}{3}}: \sqrt{\frac{5}{3}}: \sqrt{\frac{7}{5}}

\sqrt{\frac{7}{5}}: \sqrt{\frac{5}{3}}: \sqrt{\frac{4}{3}}
