I know that beat frequency is the difference in the frequencies of two superposing notes. But here 3 wave frequencies are given the difference between the first 2 is 3 while between 203, 207 is 4 .How to find the beat frequency of all 3 waves together? I have even tried finding beat frequency of the lowest and highest frequency and got 7 but still it's not the answer.how to solve these kinds sum any little help will be greatly helpful :)
