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.

40/20+x = 1/2.
Cross multiple;
80 = 20 + x.
x = 60.
Cross multiple;
80 = 20 + x.
x = 60.

To change a 60-litre milk: water mixture from a 2:1 ratio (40L milk, 20L water) to a 1:2 ratio, add 60 litres of water so the final mixture (40L milk, 80L water) has twice as much water as milk. And moreover, if we see the ratio to be converted is 1:2.
Then the quantity of water to be added is 60l.
Then the quantity of water to be added is 60l.

First, the ratio is 2:1 is 40: 20,
New ratio is 1: 2 is 20:40.
We want the water so we can add water such that 20+40=60.
New ratio is 1: 2 is 20:40.
We want the water so we can add water such that 20+40=60.

In 2:1 ratio milk +water=40 + 20 = 60 then,
In 1:2 ratio milk+water=20 + 40 = 60 now only total of water from both ratio is 60.
In 1:2 ratio milk+water=20 + 40 = 60 now only total of water from both ratio is 60.

1+2 = 3.
60/3 = 20.
Water value is change,
But milk remains the same so,
2:1
(1:2)*2= 2:4.
Change in water 4-1 = 3.
Hence,
3*20 = 60.
60/3 = 20.

Milk 2x:1x water.
Previously 2x+1x=60 litres.
3x=60L.
x=60/3=20litrs.
Previously values = milk - > 2*x=40L.
Water->1*x=20L.
Quantity to be further added in water=x.
40/20+x=1/2.
X=60 L.
Previously 2x+1x=60 litres.
3x=60L.
x=60/3=20litrs.
Previously values = milk - > 2*x=40L.
Water->1*x=20L.
Quantity to be further added in water=x.
40/20+x=1/2.
X=60 L.
