       If 20% of A =30% of B\[=\frac{1}{6}\]of C, then A : B : C is

A) 2 : 3 : 16

B) 3 : 2 : 16

C) 10 : 15 : 18

D) 15 : 10 : 18

Correct Answer: D

Solution :

20% of A = 30% of B = \[\frac{1}{6}\]of C

\[\Rightarrow \]\[\frac{20A}{100}=\frac{30B}{100}=\frac{C}{6}\Rightarrow \frac{A}{5}=\frac{B}{\frac{10}{3}}=\frac{C}{6}=k\](let)

\[\Rightarrow \] \[A=5k,\]B \[=\frac{10}{3}k,\]C\[=6k\]

\[\therefore \] A : B : C 5 k : \[\frac{10\,\,k}{3}:6k=15:10:18\]
