If `m` be the A.M. and `g` be the G.M. of two positive numbers 'a' and 'b' such that `m:g=1:2`, then `(a)/(b)` can be equal to

If h be the H.M. and g be the G.M. of two positive numbers 'a' and 'b' such that h:g=4:5 , then (a)/(b) can be equal to

If A and G be the A .M and G.M between two positive numbers, then the numbers are

The A.M. of two positive numbers is 15 and their G.M. is 12 what is the larger number?

The A.M. of two positive numbers is 15 and their G.M is 12. What is the smaller number ?

Prove that the A.M. of two positive real numbers is greater than their G.M.

If the A.M. and G.M. of two numbers are 16 and 12 respectively find their H.M.

If both the A.M. between m and n and G.M. between two distinct positive numbers a and b are equal to (ma+nb)/(m+n) , then n is equal to
