The problem involves a mixture of milk and water. We are given the initial total volume and the ratio of milk to water. We need to find out how much milk must be added to change the ratio to a new specified value, while the amount of water remains constant.
Calculate initial quantities of milk and water:
The total volume of the mixture is 25 litres.
The initial ratio of milk to water is 4:1. This means for every 4 parts of milk, there is 1 part of water, making a total of \(4+1=5\) parts.
Amount of milk initially:
\[ \text{Milk} = \frac{4}{5} \times 25 \text{ litres} = 20 \text{ litres} \]Amount of water initially:
\[ \text{Water} = \frac{1}{5} \times 25 \text{ litres} = 5 \text{ litres} \]Set up the equation for the new ratio:
Let \(x\) be the amount of milk added to the mixture.
The new amount of milk will be \( (20 + x) \) litres.
The amount of water remains unchanged, which is 5 litres.
The new ratio of milk to water is given as 16:1.
So, we can write the equation:
\[ \frac{\text{New Milk}}{\text{Water}} = \frac{16}{1} \] \[ \frac{20 + x}{5} = \frac{16}{1} \]Solve for \(x\):
Cross-multiply to solve for \(x\):
\[ 1 \times (20 + x) = 16 \times 5 \] \[ 20 + x = 80 \]Subtract 20 from both sides:
\[ x = 80 - 20 \] \[ x = 60 \text{ litres} \]Therefore, 60 litres of milk must be added.
Correct Option: C) 60
Adding 60 litres of milk makes the total milk \(20 + 60 = 80\) litres. The water remains 5 litres. The new ratio is \(80:5\), which simplifies to \(16:1\), as required.
