Beats

A set of $14$ tuning forks is arranged in a series of increasing frequencies. Each fork produces ' $x$ ' beats per second with the preceding fork and the last fork is an octave of the first fork. If the seventh fork has the frequency of $114$ Hz, the value of $x$ is

Show answer and solution

Answer: (c)

Last (14th) fork $= f + 13x = 2f \Rightarrow f = 13x$
7th fork $= f + 6x = 19x = 114 \Rightarrow x = 6$
So the answer is (c) $6$ .
