6Hz
Almost the same frequency and are sounded together.
Number of beats heard in one second will be got by the difference between the parent frequencies. Hope you have given wrong data for parent frequencies. The first one has to be 220 Hz and the other is 226 Hz. Hence 6 beats will be heard in one second. If you say 20 is the right one then difference will be 206. If 206 beats get produced in one second it will not be named as beat at all. Moreover our hearing could not recognize this as beating at all. So better correct the given data.
Could be 259 Hz.Could be 267 Hz.
The beats are the sum and difference of the components ... (A + B) and (A - B).If something really non-linear is also going on, you also get (2A - B), but we'llleave that alone for right now.That pair of forks produces beats at 2 Hz and 990Hz .
11.3 beats

A tuning fork is a two-pronged steel device that is used by musicians. When a 1056-Hz tuning fork is struck at the same time a piano note is played, and 3 beats per second is emitted, the frequency of the piano is 1059 Hz.

By tuning musical instrument we mean that to produce a note of Desired frequency. Take a standard musical instrument of well defined frequency. The new musical instrument and the standard instrument are sounded together. Initially we will hear mixed sound due to slightly frequency difference between them. The frequency of the musical instrument is gradually adjusted till we will hear same sound. When this happens, the musical instrument Will produce the note of desired frequency and is said to be turned. In this way, beats become useful in tuning a musical instrument.

A sound known as a "beat frequency" will be heard when two sounds of almost (but not quite) the same frequency are mixed together. This is commonly heard when tuning a stringed instrument (such as a guitar) into itself, or when tuning to a standard pitch generator. If the string is vibrating at exactly the same frequency as the standard, then no beat frequency is heard. If the string is vibrating at a just slightly different frequency from the standard, then the interference between the two sounds is heard as a regular "beat". The frequency of the beat is exactly equal to the difference between the two frequencies i.e. if the standard is 440 Hz and the string is vibrating at 441 Hz, then a beat frequency of 1 Hz will be heard.

The two frequencies should be near one another.
