Correct Answer - Option 1 : 58.33%
Given:
The mixture is 50 litres.
The percentage of milk in the mixture is 50%
Calculation:
According to the question, we have,
The quantity of Milk in 40 litres of the mixture,
⇒ 50 × (50/100)
⇒ 25 litres
The quantity of water in 40 litres of mixture
⇒ 50 - 25
⇒ 25 litres
Now, after adding 10 litres of water to the mixture,
New quantity of mixture = 50 + 10
⇒ 60 litres
The quantity of water = 25 + 10
⇒ 35 litres
Percentage of water in the new mixture,
⇒ (35/60) × 100
⇒ 58.33%
∴ The percentage of water in the new mixture is 58.33%.
