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.

Old: 2:1 mix = 60.
New: (1:2)*2 = 2:4.
Water added = (1*60)/4-1 = 20.
New mix = 20+40 = 60.
New: (1:2)*2 = 2:4.
Water added = (1*60)/4-1 = 20.
New mix = 20+40 = 60.

ANOTHER WAY WE CAN SOLVE BY,
Let quantity of water to be added further be x litres.
2:1
1:2 :: 60:x.
(2/1)*(1/2) = 60/x.
x = 60.

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 %?

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.

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