- a)4.54%
- b)4.64 %
- c)4.44 %
- d)4.34 %
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
A sample of milk diluted with water has a density of 1040 kgm-3. If pu...
Density of pure milk = 1080 Kg /m³
1080 kg / m³ = 100% pure milk
Density of diluted milk = 1032 kg / m³
1032 Kg/m³ = ? % of milk
1032 x 100/1080 = 95.56% of milk
Thus, the percentage of water by volume in milk is 100 – 95.56 = 4.44%
1080 kg / m³ = 100% pure milk
Density of diluted milk = 1032 kg / m³
1032 Kg/m³ = ? % of milk
1032 x 100/1080 = 95.56% of milk
Thus, the percentage of water by volume in milk is 100 – 95.56 = 4.44%

Given: Density of diluted milk = 1040 kg/m³
Density of pure milk = 1080 kg/m³
Let's assume that x% of the volume of milk is water.
So, the remaining (100-x)% of the volume is pure milk.
Now, we can use the concept of density to form an equation as follows:
Density of diluted milk = (100-x)% × Density of pure milk + x% × Density of water
We know the values of the densities of diluted milk and pure milk. Also, the density of water is 1000 kg/m³.
Substituting the given values in the above equation, we get:
1040 = (100-x)% × 1080 + x% × 1000
Simplifying this equation, we get:
1040 = 1080 - 8x + 10x
40 = 2x
x = 20
Therefore, the percentage of water by volume in milk is:
x% = 20%
or
x/100 = 0.2
Converting this into percentage, we get:
x% = 20%
Therefore, option (c) 4.44% is incorrect. The correct answer is option (b) 4.64%.
Density of pure milk = 1080 kg/m³
Let's assume that x% of the volume of milk is water.
So, the remaining (100-x)% of the volume is pure milk.
Now, we can use the concept of density to form an equation as follows:

We know the values of the densities of diluted milk and pure milk. Also, the density of water is 1000 kg/m³.
Substituting the given values in the above equation, we get:
1040 = (100-x)% × 1080 + x% × 1000
Simplifying this equation, we get:
1040 = 1080 - 8x + 10x
40 = 2x
x = 20
Therefore, the percentage of water by volume in milk is:
x% = 20%
or
x/100 = 0.2
Converting this into percentage, we get:
x% = 20%
Therefore, option (c) 4.44% is incorrect. The correct answer is option (b) 4.64%.
