1.	If a, b, c are in geometric progression then a/b = A) c/bB) b/cC) b/aD) a/c
Answer» Correct option is (B) b/c a, b, c are in G.P. \(\therefore b=ar\) and \(c=ar^2\) \(\Rightarrow r=\frac ba\) and \(\frac cb=\frac{ar^2}{ar}=r=\frac ba\) \(\therefore\) \(\frac{a}{b}\) = \(\frac{b}{c}\) Correct option is B) b/c

If a, b, c are in geometric progression then a/b = A) c/bB) b/cC) b/aD) a/c

Answer»

Correct option is (B) b/c

a, b, c are in G.P.

\(\therefore b=ar\)

and \(c=ar^2\)

\(\Rightarrow r=\frac ba\)

and \(\frac cb=\frac{ar^2}{ar}=r=\frac ba\)

\(\therefore\) \(\frac{a}{b}\) = \(\frac{b}{c}\)

Correct option is B) b/c
