Question

A mixture 40 litre contains milk and water in 3:5. From this mixture 8 litre was withdrawn and replaced by 4 litre water. Then find ratio of milk and water

Answer 1

Answer:

by this process we get the answer

Answer 2

Answer: The ratio of milk and water is 1:2.

Step-by-step explanation:

Since we have given that

Quantity of mixture = 40 liters

Ratio of milk and water = 3:5

So, Quantity of milk in mixture is given by

$\dfrac{3}{8}\times 40\\\\=3\times 5\\\\=15\ ltrs$

Quantity of water in mixture is given by

$\dfrac{5}{8}\times 40\\\\=5\times 5\\\\=25\ ltrs$

Now, Quantity of mixture is withdrawn = 8 ltrs

So, Quantity of milk is withdrawn is given by

$\dfrac{3}{8}\times 8\\\\=3\ ltrs$

Quantity of water is withdrawn is given by

$\dfrac{5}{8}\times 8\\\\=5\ ltrs$

Quantity of water is replaced = 4 liters.

According to question, ratio of milk to water becomes

$\dfrac{15-3}{25-5+4}=\dfrac{12}{24}=\dfrac{1}{2}=1:2$

Hence, the ratio of milk and water is 1:2.
