A vessel contains 60 liters of milk. 12 liters of milk taken out from it and replaced with water. Then again from mixture 12 liters is taken out and replaced with water. The ratio of milk and water in the resultant mixture is:
Answer & explanation
Correct answer: option 1
Total Milk = 60 liters
drawn off = 12 liters (two times)
(1 - \(\frac{x}{a}\))t
x = replaced quantity
a = capacity
t = number of process
Therefore,
⇒ (1 - \(\frac{12}{60}\))n = \(\frac{4}{5}\)n = \(\frac{16}{25}\) (where 16 → milk and 25 → total quantity)
Hence, Water now = 25 - 16 = 9
⇒ M : W = 16 : 9
