64 tuning forks are arranged in order of increasing frequency. The frequency of the last fork is double of the first and each two consecutive forks produce 4 beats per second. Calculate the frequency of the last fork.

32 tuning forks are arranged in order of increasing frequency such that frequency of last fork is double than first. 6 beats per second are produced by each two consecutive forks. The frequency of last fork is n xx 186 . Find the value of n. {:(0,1,2,3,4,5,6,7,8,9),(,,,,,,,,,):}

31 tuning forks are arranged in series in increasing order of frequencies and the frequency of the last tuning fork is 3 times the frequency of the first. If each tuning fork produces 4 beats/second with the preceding one, the frequency of the last tuning fork is

Fifty-one turning forks are arranged in order of increasing frequencies so that each fork gives 3 beats per second with the next. The last fork gives the fifth of the first. Calculate the frequency of the latter.

64 tuning forks are arranged in order of increasing frequency and any two successive forks give foor beats per second when sounded together. If the last fork gives the octave of the first, calculate the frequency of the latter.

65 tuning forks are arranged in order of increasing frequency. Any two successive forks produce 4 beats//s , when sounded together. If the last fork gives an octave of the first, the frequency of the first fork is

16 tuning forks are arranged in increasing order of frequency. Any two consecutive tuning forks when sounded together produce 8 beats per second. If the frequency of last tuning fork is twice that of first, the frequency of first tuning fork is :-
