A container has a mixture of milk and water in the ratio 3:1. After removing 20 liters of the mixture and adding 12 liters of water, the new ratio of milk to water becomes 2:1. What is the total volume of the original mixture?
A. 36
B. 54
C. 72
D. 92
E. 116

E. 116
Let's say the initial volume is x liters in total and we are given that Milk : Water :: 3 : 1
that means in 4 qty of total volume 3 qty is milk and 1 qty is water. So, for x qty -->
Milk = 3x/4
Water = x/4
Removing 20 liters of the mixture and adding 12 liters of water
Remember: we are removing from the mix. So, this 20 liter will have the same ratio of Milk to Water as the whole mixture = 3 : 1
That means we are removing 15 liters of milk and 5 liters of Water
Then we are adding 12 liters of water only.
resulting in
Milk = 3x/4 - 15
Water = x/4 - 5 + 12 = x/4 +7
We know that this Milk to Water ratio is 2:1 so,
( 3x/4 - 15 ) / (x/4 +7) = 2/1
3x/4 - 15 = x/2 + 14
x = 116
that means in 4 qty of total volume 3 qty is milk and 1 qty is water. So, for x qty -->
Milk = 3x/4
Water = x/4
Removing 20 liters of the mixture and adding 12 liters of water
Remember: we are removing from the mix. So, this 20 liter will have the same ratio of Milk to Water as the whole mixture = 3 : 1
That means we are removing 15 liters of milk and 5 liters of Water
Then we are adding 12 liters of water only.
resulting in
Milk = 3x/4 - 15
Water = x/4 - 5 + 12 = x/4 +7
We know that this Milk to Water ratio is 2:1 so,
( 3x/4 - 15 ) / (x/4 +7) = 2/1
3x/4 - 15 = x/2 + 14
x = 116
