If `a,b,c are in G.P. and x,y be the AM\'s between a,b and b,c respectively then (A) ``1/a+1/b=(x+y)/6``(B) ax+cy=b` (C) `a/x+c/y=2` (D) `1/x+1/y=2/b`

If a,b,c in G.P. x,y be the A.M.\'s between a,b and b,c respectively then (a/x+c/y)(b/x+b/y)= (A) 2 (B) -4 (C) 4 (D) none of these

If a, b, c are in G.P., x and y are the A.M.'s of a, b and b, c respectively, then prove that: (i)(a)/(x)+(c)/(y)=2" "(ii) (1)/(y)+(1)/(y)=(2)/(b)

If a,b,c are in G.P.and x,y are the arithmetic means of a,b and b,c respectively, then prove that (a)/(x)+(c)/(y)=2 and (1)/(x)+(1)/(y)=(2)/(b)

If a, b and c are in G.P and x and y, respectively , be arithmetic means between a,b and b,c then

If a,b, and c are in G.P.and x and y respectively,be arithmetic means between a,b, and b,c, then (a)/(x)+(c)/(y)=2b(a)/(x)+(c)/(y)=(c)/(a) c.(1)/(x)+(1)/(y)=(2)/(b) d.(1)/(x)+(1)/(y)=(2)/(ac)

If a,b,c are in A.P., a,x,b are in G.P. and b,y,c are in G.P. then a^(2),b^(2),y^(2) are in
