Question: A solution is made by mixing two liquids A and B in the ratio 4:1. If there are 25 liters of liquid A, how much liquid B is needed?

Options:

Correct Answer: 5 liters

Solution:

If A:B = 4:1, then for 25 liters of A, B = (1/4) * 25 = 5 liters.

A solution is made by mixing two liquids A and B in the ratio 4:1. If there are 25 liters of liquid A, how much liquid B is needed?

Step 1: Understand the ratio of liquids A and B, which is 4:1. This means for every 4 parts of A, there is 1 part of B.
Step 2: Identify how much liquid A you have, which is 25 liters.
Step 3: Since the ratio is 4:1, we can say that for every 4 liters of A, there is 1 liter of B.
Step 4: To find out how much B is needed for 25 liters of A, we can set up a proportion. If A is 4 parts, then B is 1 part.
Step 5: Calculate the amount of B needed by using the formula: B = (1/4) * amount of A.
Step 6: Substitute the amount of A into the formula: B = (1/4) * 25.
Step 7: Perform the calculation: B = 25 / 4 = 5 liters.
