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

Options:

  1. 20 liters
  2. 15 liters
  3. 10 liters
  4. 5 liters

Correct Answer: 20 liters

Solution: 

In a 4:1 ratio, the total parts = 4 + 1 = 5. Liquid A = (4/5) * 25 = 20 liters.

Questions & Step-by-Step Solutions

A solution is made by mixing two liquids A and B in the ratio 4:1. If there are 25 liters of the solution, how much liquid A is present?
  • 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: Calculate the total number of parts in the mixture. Add the parts of A and B together: 4 (for A) + 1 (for B) = 5 total parts.
  • Step 3: Determine how much one part is worth in the total solution. Since the total solution is 25 liters, divide 25 by the total parts: 25 liters / 5 parts = 5 liters per part.
  • Step 4: Calculate the amount of liquid A. Since liquid A has 4 parts, multiply the value of one part by 4: 5 liters/part * 4 parts = 20 liters of liquid A.
