A set of 56 tuning forks are so arranged in series that each fork gives 4 beats per second with the previous one. The frequency of the last fork Is 3 times that of the first. The frequency of the first fork is

56 tuning forks are so arranged in series that each fork gives 4 beats per second with the previous one.The frequency of the last fork is three times that of the first.The frequency of the fork is

A set of 56 tuning forks are so arranged in series that each fork given 4 beats per second with previous one.The frequency of last fork 1.5 times that of the first. The frequency f 50th fork is:

56 tuning forks are arranged such that each fork produces 4 beats per second with its preceding fork. The frequency of the last fork is three times that of first . The frequency of first fork will be

A set of 56 tuning forks is arranged in series of increasing frequencies.If each fork gives 4 beats with preceding one and the frequency of the last in twice that of first ,then frequency of the first fork is

A set of 11 tuning forks is kept in ascending order of frequencies. Each tuning fork gives 5 beats per second with the previous one. If the frequency of the last fork is 1.5 times that of the first , find the frequency of the first and last fork.

A set of 48 tuning forks is arranged in a series of descending frequencies such that each fork gives 4 beats per second with preceding one.The frequency of first fork is 1.5 times the frequency of the last fork, find the frequency of the first and 42^nd tuning fork.

A set of 28 tuning forks is arranged in a series of decreasing frequencies.Each fork girves 4 beats per second with the preceding one and the frequencies of the first forks is an octave of the last.The frequency of the first fork in Hz is

Eleven tuning forks are arranged in the ascending order of frequencies .Each tuning fork gives 4 beats per second with the preceding fork. If the frequency of the last fork is twice that of the first , find the frequency of the first , last and fifth fork.

A set of 31 tuning forks is arranged in series of decreasing frequencies. Each fork gives 6 beats per second with the proceeding one and frequency of the first fork is twice the frequency of the last. Find the frequency of the first and the last tuning fork.
