Question

AM: GM= 5:4 if the difference between GM and HM is -4/5 find the numbers

Answer 1

Geometric Mean If two numbers a and b are in GP, then their GM =Jab In general, if a, b, c, ..., n terms are in GP, then GM =Jax bacon terms So, if three terms a, b and c are in GP, then their GM = b = Wax boxc Harmonic Mean If two numbers a and b are in HP, then their HM 2ab a +b Relationship Among AM, GM and HM ...
 using this formula we can find it try otherwise  i will send the answer withstep later
