Two vessels A and B contains milk and water in the ratio of 8 : 5 and 5 : 2, respectively. The ratio in which these two be mixed to get a new mixture containing 69\(\frac{3}{13}\) % milk is?
Answer & explanation
Correct answer: option 4
*[23\(\frac{1}{13}\) % = \(\frac{3}{13}\)]*
therefore, [69\(\frac{3}{13}\) % = \(\frac{9}{13}\)]
[\(\frac{Milk}{Water}\) = \(\frac{9}{4}\)]
Milk Water Total
I → 8 : 5 → 13 (×7
II → 5 : 2 → 7 (×13
9 : 4 → 13 (×7 ← (Required ratio)
Make total quantity equal.
Use Alligation method on milk only
Therefore, mixtures should be mixed in the ratio 2: 7
