If three pure signals with frequencies of 100, 200, and 500 Hz are added, their sum is a signal with a
frequency of 100 Hz, which has additional "wiggles" superimposed on its shape. The Wiggles appear in
groups of 2 per cycle and 5 per cycle on the main signal; their exact shape and depth is determined by
the relative amplitudes of the three individual component signals.
Look for a common factor for the frequencies you specified. Obviously the answer isn't 100 (the lowest number in the list), since 150 and 250 are not multiples of 100, therefore you should look for a smaller number, that IS a common factor to all these numbers.
-100 + 200 = 100
Watch closely:50/200 = 0.25 = 25 %

A sitar typically has a frequency range of about 150 Hz to 5000 Hz. The lower strings produce frequencies around 200-300 Hz, while the higher strings produce frequencies around 1000-5000 Hz, creating a wide frequency range that contributes to the unique sound of the instrument.
The frequency range of a maracas typically falls within the percussion instrument category, producing a wide range of frequencies. The lowest frequencies produced by a maracas are around 200 Hz, while the highest frequencies can reach up to 10,000 Hz or more. This wide range of frequencies is due to the varying sizes and materials used in the construction of maracas, allowing for a diverse sound profile.

harmonics is nothing but an unwanted noise or ripples.A harmonic of a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency. If the fundamental frequency is f, the harmonics have frequencies f, 2f, 3f, 4f, etc. For example, if the fundamental frequency is 50Hz, the frequencies of the harmonics are: 50 Hz, 100 Hz, 150 Hz, 200 Hz, etc. Don't forget: Even harmonics 2f, 4f, 6f,... are odd overtones. Odd harmonics f, 3f, 5f,... are even overtones. Scroll down to related links and look at "Calculations of harmonics from fundamental frequency".
100 is 50% of 200.

The human ear is capable of detecting sound at frequencies between about 20 and 20,000 Hz. Within this frequency range, however, the response of the ear is not uniform. The ear is most sensitive to frequencies between 200 and 4000 Hz, and its response decreases toward both higher and lower frequencies. There are wide variations in the frequency response of individuals. Some people cannot hear sounds above 8000 Hz, whereas a few people can hear sounds above 20,000 Hz. Furthermore, the hearing of most people deteriorates with age. The sensation of pitch is related to the frequency of the sound. The pitch increases with frequency. Thus, the frequency of middle C is 256 Hz, and the frequency of the A above is 440 Hz. There is, however, no simple mathematical relationship between pitch and frequency. frequency causes the different types of pitch
The missing resonant frequency below 200 Hz is 150 Hz. This can be determined by observing that the given resonant frequencies are spaced evenly at intervals of 50 Hz, and 150 Hz fits this pattern.
It is: 200/100 times 100 = 200%

Harmonics are integer multiples of the fundamental frequency in a sound. For example, if the fundamental frequency is 100 Hz, the first harmonic is 200 Hz (2 x 100 Hz), the second harmonic is 300 Hz (3 x 100 Hz), and so on. Together, they create the overall timbre or tonal quality of the sound.
