Show Answer
Answer:
Correct Answer: D
Solution:
- 20% of $ A=30% $ and $ 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 $
$ \Rightarrow $ $ A=5k, $ $ B=\frac{10}{3}k $ and $ C=6k $
$ \therefore $ $ A:B:C=5k:\frac{10k}{3}:6k=15:10:18 $
