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.

Quantity of mixture is 60 liters.
Ratio = 2:1 so, 40 milk : 20 water.
Take the same quantity of mixture 60 liters. Ratio = 1:2.
So, 20 milk : 40 water. Therefore the total quantity of water = 40+20 = 60.
Ratio = 2:1 so, 40 milk : 20 water.
Take the same quantity of mixture 60 liters. Ratio = 1:2.
So, 20 milk : 40 water. Therefore the total quantity of water = 40+20 = 60.

You can apply 4th std formula:
Ratio:
2/1.
1/2.
Liter:
60.
(?).
Then 1/2x60x2/1 = 60.
Ratio:
2/1.
1/2.
Liter:
60.
(?).
Then 1/2x60x2/1 = 60.

2:1 ratio.
M:W
For milk: 2/3*60 = 40 lts milk.
For water: 60-40 = 20 lts water.
1:2 ratio.
M:W.
For water: 2/3*60 = 40 ltrs water.
What he is asked total water mixture i.e 20+40 = 60?

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.
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 %?
