If A : B = \(\frac{1}{2}\) : \(\frac{5}{6}\) , B : C = \(\frac{1}{3}\): \(\frac{4}{3}\) and C : D = \(\frac{2}{3}\) : \(\frac{10}{9}\) then A : B : C : D equal to:
Answer & explanation
Correct answer: option 4
A : B = \(\frac{1}{2}\) : \(\frac{5}{6}\) = 3 : 5
B : C = \(\frac{1}{3}\) : \(\frac{4}{3}\) = 1 : 4
C : D = \(\frac{2}{3}\) : \(\frac{10}{9}\) = 6 : 10 = 3 : 5
A : B : C : D
3 : 5
1 : 4
3 : 5
