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 A.M. between a, b and b, c respectively, prove that, (a)/(x) + (c )/(y) = 2

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. and x, y be the A.M. between a, b and b, c respectively, prove that, (1)/(x) + (1)/(y) = (2)/(b)

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

a, b, c are in G.P. and x and y are the A.M.’s between a, b and b, c respectively. Show that : a/x+c/y=2 .

a, b, c are in G.P. and x and y are the A.M.’s between a, b and b, c respectively. Show that : 1/x+1/y=2/b .

a, b, c are in G.P. If x, y are A.M.'s between a, b and b, c respectively, prove that- a/x+c/y=2 and 1/x+1/y=2/b .

If a,b,c are in G. P. and x, y are A.M. of a, b and b, c respectively, then the value of ((a)/(x)+ (c )/(y)) is-

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)/(x)+(1)/(y)=(2)/(b)
