What was the original frequency of the guitar string

Reference no: EM13981279

A piano is tuned to a frequency of 440.00 Hz. When it and the G string of a guitar are sounded together, 30 beats are heard every 20 seconds. The beats become slower as the guitar string is slowly tighthened. (As the string is tightened, there are fewer beats/second). What was the original frequency of the guitar string?
