Aptitude Question ID : 93612

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 : 4 : 8 : 10
[D]6 : 8 : 9 : 10

8 : 6 : 10 : 9
A : B = \frac{1}{2}:\frac{3}{8} = 4:3 = 8 : 6
B:C = \frac{1}{3}: \frac{5}{9} = 3 : 5 = 6 : 10
C:D = \frac{5}{6}:\frac{3}{4} = 10:9
A:B:C:D = 8:6:10:9
Hence option [B] is the right answer.
