If $A:B=\frac{1}{2}:\frac{5}{8}, B:C=\frac{1}{3}:\frac{4}{5}$ and $C:D=\frac{3}{4}:\frac{5}{16}$, then the ratio $A: B: C: D$ is:
Answer & explanation
Correct answer: option 3
Answer :- (C) 4 : 5 : 12 : 5
A : B = \(\frac{1}{2}\) : \(\frac{5}{8}\) = 4 : 5
B : C = \(\frac{1}{3}\) : \(\frac{4}{5}\) = 5 : 12
C : D = \(\frac{3}{4}\) : \(\frac{5}{16}\) = 12 : 5
Overall, A : B : C : D = 4 : 5 : 12 : 5
