Consider three mixtures - the first having water and liquid A in the ratio 1 : 2, the second having water and liquid B in the ratio 1 : 3, and the third having water and liquid C in the ratio 1 : 4. These three mixtures of A, B, and C, respectively, are further mixed in the proportion 4:3:2. Then the resulting mixture has
  • a)
    The same amount of water and liquid B
  • b)
    same amount of liquids B and C
  • c)
    More water than liquid B
  • d)
    More water than liquid A
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
Consider three mixtures - the first having water and liquid A in the r...
Mixtures A, B, & C are mixed in the ratio 4 : 3 : 2
--> Let the volumes = 4k, 3k, 2k respectively
Mixtures ---- Ratio ---- Water ------ Liquid
Mixture A --- 1 : 2 ---- 4k(1/3) ---- 4k(2/3)
Mixture B --- 1 : 3 ---- 3k(1/4) ---- 3k(3/4)
Mixture C --- 1 : 4 ---- 2k(1/5) ---- 2k(4/5)
Assume k = 60 [LCM(3, 4, 5) = 60]
Volume of Liquid A = 8k/3 = 160
Volume of Liquid B = 9k/4 = 135
Volume of Liquid C = 8k/5 = 96
Volume of water = 4k/3 + 3k/4 + 2k/5 = 80 + 45 + 24 = 149
--> There is more water than Liquid B

Consider three mixtures - the first having water and liquid A in the r...
To solve this problem, we need to consider the ratios of the mixtures and the proportions in which they are further mixed. Let's break down the problem step by step:

Step 1: Initial Mixtures
The three initial mixtures are:
- Mixture 1: Water and liquid A in the ratio 1:2
- Mixture 2: Water and liquid B in the ratio 1:3
- Mixture 3: Water and liquid C in the ratio 1:4

Step 2: Further Mixing
The three initial mixtures are further mixed in the proportion 4:3:2, respectively. This means that for every 4 units of mixture 1, 3 units of mixture 2, and 2 units of mixture 3 are mixed together.

Step 3: Calculating the Resulting Mixture
To calculate the resulting mixture, we need to determine the ratio of water to liquid in the mixture. Let's calculate it:

- Mixture 1 contains water and liquid A in the ratio 1:2. So, for every 1 unit of water, there are 2 units of liquid A.
- Mixture 2 contains water and liquid B in the ratio 1:3. So, for every 1 unit of water, there are 3 units of liquid B.
- Mixture 3 contains water and liquid C in the ratio 1:4. So, for every 1 unit of water, there are 4 units of liquid C.

Now, let's calculate the total amount of water and liquid in the resulting mixture:

- Water: (4 units of mixture 1) + (3 units of mixture 2) + (2 units of mixture 3) = 4 + 3 + 2 = 9 units of water
- Liquid A: 2 units of mixture 1 = 2 units
- Liquid B: 3 units of mixture 2 = 3 units
- Liquid C: 4 units of mixture 3 = 4 units

Step 4: Comparing the Amounts
From the calculations above, we can see that the resulting mixture has more water (9 units) than any of the liquids A, B, or C. Therefore, the correct answer is option C: "More water than liquid B".

The resulting mixture is 9:25 ( jus multiplying )

which is less water then a ( 4th not satisfied ) but more water than we (c satisfied as 1:3 is 9:27)
