If A : B = $$\frac{1}{2}$$ : $$\frac{3}{8},$$ B : C = $$\frac{1}{3}$$ : $$\frac{5}{9}$$ and C : D = $$\frac{5}{6}$$ : $$\frac{3}{4},$$ then the ratio A : B : C : D is
A. 4 : 6 : 8 : 10
B. 8 : 6 : 10 : 9
C. 6 : 8 : 9 : 10
D. 6 : 4 : 8 : 10
Answer: Option B
Solution(By Examveda Team)
$$\eqalign{ & {\text{A}}:{\text{B}} = \frac{1}{2}:\frac{3}{8} = 4:3, \cr & {\text{B}}:{\text{C}} = \frac{1}{3}:\frac{5}{9} = 3:5, \cr & {\text{C}}:{\text{D}} = \frac{5}{6}:\frac{3}{4} = 10:9 \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = 5:\frac{9}{2}. \cr & \therefore {\text{A}}:{\text{B}}:{\text{C}}:{\text{D}} \cr & = 4:3:5:\frac{9}{2} \cr & = 8:6:10:9. \cr} $$Related Questions on Ratio
