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. 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 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. , a.x.b in A.P. and b,y,c in A.P., then : (a)/(x)+( c )/(y) = (A) 1/2 (B) 1 (C) 2 (D) none of these

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)

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

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

If a,b,andc are in G.P.and x,y, respectively,are the arithmetic means between a,b, and b,c ,then the value of (a)/(x)+(c)/(y) is 1 b.2 c.1/2 d.none of these
