56 tuning forks are so arranged in series that each fork give 4 beats per sec with the previous one. The frequency of the last fork is 3 times that of the first. The frequency of the first 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 24 tuning forks are so arranged that each gives 6 beats per second with the previous one. If the frequency of the last tuning fork is double that of the first, frequency of the second tuning 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.
