Guys i think we follow the rules.

 

When values are given as x per y where x is constant and y is variable, the Harmonic Mean is the appropriate
average to use.
•  When values are given as x per y where y is constant and x is variable, the Arithmetic Mean is the appropriate
average to use.
•  When relative changes in some variable quantity are to be averaged, the geometric mean is the appropriate
average to use.

iss k mutabik toh hamaray question ka mean banay ga Harmonic mean. or Harmonic mean ka formula hay.
H.M = n/∑1/x
1/120 + 1/125 + 1/104 = .0083+ .008 + .0096 =0.0259
so hamara result banay ga  = 3/0.0259 = 115.83
or isko ham 15.83 % increase likh saktay hain.
