If `A_1, A_2` be two A.M. and `G_1, G_2` be two G.M.s between `aa n db` then `(A_1+A_2)/(G_1G_2)` is equal to `(a+b)/(2a b)` b. `(2a b)/(a+b)` c.`(a+b)/(a b)` d. `(a+b)/(sqrt(a b))`

If A_(1),A_(2) be two A.M.'s and G_(1),G_(2) be two G.M.,s between a and b, then (A_(1)+A_(2))/(G_(1)G_(2)) is equal to

If A_1,A_2 be two A.M.\'s G_1,G_2 be the two G.M.\'s and H_1,H_2 be the two H.M.\'s between a and b then (A) (A_1+A_2)/(G_1 G_2)=(a+b)/(ab) (B) (H_1+H_2)/(H_1 H_2)=(a+b)/ab (C) (G_1G_2)/(H_1 H_2)=(A_1+A_2)/(H_1+H_2) (D) (A_1+A_2)/(H_1 H_2)=(a+b)/(a-b)

If a be one A.M and G_(1) and G_(2) be then geometric means between b and c then G_(1)^(3)+G_(2)^(3)=

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_(1) and A_(2) are two A.M.s between a and b and G_(1) and G_(2) are two G.M.s between the same numbers then what is the value of (A_(1)+A_(2))/(G_(1)G_(2))

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 A1,A2,G1,G2 and H1,H2 are two A.M's , G.Ms and H.M.'s between two numbers,then (A_(1)+A_(2))/(H_(1)+H_(2))*(H_(1)H_(2))/(G_(1)G_(2))

If a is the A.M. between b and c, b the G.M. between a and c, then show that 1/a,1/c,1/b are in A.P.
