If G.M. of 3 and y is 6, then y=?

If A.M. and G.M. of x and y are in the ration p : q, then x:y is :

If A.M and G.M of x and y are in the ratio p:q , then x:y is

a, b, c are in A.P. If x be the G.M. of a and b, and y be the G.M. of b and c, then prove that b^2 is the A.M. of x_2 and y_2 .

If x prop y and y prop z, then show that (x^m+y^m+z^m) prop (x^3y^(m-3) +y^3z^(m-3)=z^3x^(m-3)) (m = constant)

G.M. of 3, 6, 24, 48 is

If x,y,z be three numbers in G.P. such that 4 is the A.M. between x and y and 9 is the H.M. between y and z , then y is

If x,y,z be three numbers in G.P. such that 4 is the A.M. between x and y and 9 is the H.M. between y and z , then y is

If x,y,z be three numbers in G.P. such that 4 is the A.M. between x and y and 9 is the H.M. between y and z , then y is

If x,y,z be three numbers in G.P. such that 4 is the A.M. between x and y and 9 is the H.M. between y and z , then y is

a, b, c are in A . P, x is G . M between a and b, y is the G.M between b and c, then b^(2) is
