Bottle 1 contains a mixture of milk and water in 7 : 2 ratio and Bottle 2 contains a mixture of milk and water in 9 : 4 ratio. In what ratio of volumes should the liquids in Bottle 1 and Bottle 2 be combined to obtain a mixture of milk and water in 3 : 1 ratio?

B) 27 : 13
C) 27 : 16
D) 27 : 18
Answer
Option (B)
Solution
From CAT 2017 – Quantitative Aptitude – Arithmetic – Mixtures, we can see that,
Volume of Bottle 1 = A
Volume of bottle 2 = B
Ratio in which mixtures of Bottle 1 and Bottle 2 will be mixed
(7A/9 + 9B/13)/ (2A/9+4B/13) = 3/1
On solving we get, A/B = 27/13
