The Correct Option is C

Solution and Explanation

The correct answer is (C):
First mixture has 2/3rds A and the rest water. Second mixture has 3/4ths B and the rest water. Third mixture has 4/5ths C and the rest water.
The 3 mixtures are mixed in the ratio 4 : 3 : 2. Let’s say we get a 1 litre mixture containing the three mixtures.
There will be 4/9(2/3)rd A, 3/9(3/4)th B and 2/3(4/5)th
C. (the remaining part would be water)
8/27 litres A, 9/36 litres B, 8/45 litres C
Water = 1-[8/27+9/36+8/45] = 149/540 litres
We can see that 149/540<8/27 and 149/540>9/36
∴ There is more water than B in the resultant solution.
