Question: If a mixture of two liquids A and B is in the ratio 4:1, how much of liquid B is present in 100 liters of the mixture?

Options:

Correct Answer: 20 liters

Solution:

The total parts in the mixture is 4 + 1 = 5. Liquid B is (1/5) * 100 = 20 liters.

If a mixture of two liquids A and B is in the ratio 4:1, how much of liquid B is present in 100 liters of the mixture?

If a mixture of two liquids A and B is in the ratio 4:1, how much of liquid B is present in 100 liters of the mixture?

Step 1: Understand the ratio of liquids A and B, which is 4:1. This means for every 4 parts of liquid A, there is 1 part of liquid B.
Step 2: Add the parts of the ratio together. 4 (for A) + 1 (for B) = 5 total parts.
Step 3: Determine how much of the total mixture (100 liters) corresponds to liquid B. Since liquid B is 1 part out of 5 total parts, we calculate (1/5) of 100 liters.
Step 4: Calculate (1/5) * 100 = 20 liters. This is the amount of liquid B in the mixture.
