A tuning fork of frequency 256 Hz gives 5 beats // s with a vibrating string of a piano. The beat frequency decreases to 2, when tension in the string is slightly increased. What was the frequency of the piano string before increasing the tension ?

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 :-
