Two vessels of equal capacity, and both completely filled, contain mixtures of milk and water in the ratio of 5 : 1 and 6 : 5, respectively. Both the mixtures are now mixed thoroughly. What is the ratio of milk to water in the new mixture so obtained?
Answer & explanation
Correct answer: option 3
Solution A,
M : W
5 : 1
Solution B,
M : W
6 : 5
⇒ Making quantity equal of both solution, we multiply Sol. A with 11 and Sol. B with 6,
⇒ (5 : 1) x 11 = 55 : 11 and (6 : 5) x 6 = 36 : 30
⇒ Adding both the solutions, we get
⇒ (55 + 36) : (11 + 30) = 91 : 41
⇒ Milk : Water = 91 : 41
