A source of frequency n given 5 beats $s^{- 1}$, when sounded with a source of frequency 200 $s^{- 1}$. The second harmonic (2n) gives 10 beats $s^{- 1}$, when sounded with a source of frequency 420 $s^{- 1}$. $n$ is equal to

(b) Here,$\ n = 200 \pm 5\ and\ 2\ n = 420 \pm 10$. This is possible only when $n = 200 + 5 = 205$
