Show Answer
Answer:
Correct Answer: B
Solution:
- Given, ratio of milk and water in first vessel = 3 : 2
$ \therefore $ Part of milk in 1 st vessel $ =\frac{3}{5} $ $ [ by\frac{a}{a+b} ] $ and ratio of milk and water in second vessel =7 : 3
$ \therefore $ Part of milk in second vessel $ =\frac{7}{10} $ and new mixture ratio = 2 : 1 By alligation rule
$ \therefore $ Required ratio $ =\frac{1}{30}:\frac{1}{15}=1:2 $
