Question: A mixture contains 40% milk and 60% water. If 20 liters of water is added, what will be the new ratio of milk to water?

Options:

Correct Answer: 5:4

Solution:

Initial milk = 40% of 100L = 40L, water = 60% of 100L = 60L + 20L = 80L. New ratio = 40:80 = 1:2.

A mixture contains 40% milk and 60% water. If 20 liters of water is added, what will be the new ratio of milk to water?

Step 1: Understand the initial mixture. It has 40% milk and 60% water.
Step 2: Assume the total volume of the mixture is 100 liters for easy calculation.
Step 3: Calculate the amount of milk in the mixture. 40% of 100 liters is 40 liters of milk.
Step 4: Calculate the amount of water in the mixture. 60% of 100 liters is 60 liters of water.
Step 5: Add 20 liters of water to the existing amount of water. So, 60 liters + 20 liters = 80 liters of water.
Step 6: Now, we have 40 liters of milk and 80 liters of water.
Step 7: Find the new ratio of milk to water. The ratio is 40 liters of milk to 80 liters of water.
Step 8: Simplify the ratio. 40:80 can be simplified to 1:2.
