If A,G,H are AM,GM,HM between the two numbers a and b ,then A ,G,H are in

If the ratio of H.M. and G.M. between two numbers a and b is 4:5, then find the ratio of the two number?

If A^(x)=G^(y)=H^(z) , where A,G,H are AM,GM and HM between two given quantities, then prove that x,y,z are in HP.

If sum of A.M. and H.M between two numbers is 25 and their GM is,then sum of two numbers

If A_1,A_2,G_1,G_2 and H_1,H_2 are AM’s, GM’s and HM’s between two numbers, then (A_1+A_2)/(H_1+H_2). (H_1H_2)/(G_1G_2) equals _____

If A,G,H are A.M., G.M., H.M. respectively, if G=6 and H=4 then value of A is

Two AMs. A_1 and A_2 , two GMs. G_1 and G_2 and two HMs. H_1 and H_2 are inserted between any two numbers. Then find the arithmetic mean between H_1 and H_2 in terms of A_1, A_2, G_1, G_2 .
