In a mixture 60 litres, the ratio of milk and water 2 : 1. If this ratio is to be 1 : 2, then the quantity of water to be further added is:
Answer: Option
Explanation:
| Quantity of milk = |  |
60 x | 2 |  litres = 40 litres. |
| 3 |
Quantity of water in it = (60- 40) litres = 20 litres.
New ratio = 1 : 2
Let quantity of water to be added further be x litres.
| Then, milk : water = | |
40 | |
. |
| 20 + x |
| Now, | |
40 | |
= | 1 |
| 20 + x | 2 |
20 + x = 80
x = 60.
Quantity of water to be added = 60 litres.

Alligation.
Take ratio of milk.
2/3.0.
1/3.
1/3.1/3.
Assume x as the amount of water to be added.
Therefore 60/x = 1/3 * 3/1.
X = 60.

2 : 1.
1 : 2 = 2 : 4, 3parts increases.
3parts = 60
1 : 2 = 2 : 4, 3parts increases.
3parts = 60

Very simple in inverted method says.
a : b = b : a.
i.e a/b = b/a so, answer is 60 the same.
a : b = b : a.
i.e a/b = b/a so, answer is 60 the same.

Can anybody please answer this question?
The ratio of milk to water in the first container = 5 : 1.
The ratio of milk to water in the second container = 7 : 2.
In what ratio the mixtures of this two container should be added together so that the quantity of milk in the new mixture may become 80 %?
