Question

Find two numbers such that the mean proportional between them is 18 and third proportional to them is 144

Answer 1

Answer:

Helloo!!

x/18 = 18/y 

xy = 18*18 

x/y = y/144 

x = (y^2)/144 

putting the value of x

we get,

((y^2)/144)*y = (y^3)/144 = 18*18 

y^3 = 18*18*144 

y = 36 

x = 36*36/144 

x = 9 

Therefore numbers are 9 and 36

hope this helps you
