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.

2x + x = 60.
Volume of water X = 20
Volume of milk y = 2x = 40.
Now keeping the volume of milk fixed i.e y = 40
Therefore y+2y=z,
40+(2*40)=z,
Z=120.
Therefore volume of water is 120-40=80.
But volume already present is 20 so additional water to be added is 80-20=60 litre.

With the help of first ratio 2:1 we find already milk 40 liters and 20 liters water (total 60 liter of mixture). But I don't why we taken 40 liters of milk is consider as 1 part for the new ratio (1:2). Actually in old ratio 40 liter is 2 part. Please any one clarify please.

"In a vessel, containing 60 litres of a mixture of milk and water, water is only 30%. 12 litres of the mixture were taken out and X litres of pure milk were added. As a result percentage of water in the mixture became 18%. What is the value of X?" Can anyone please explain?

Old ratio is 2:1.
New ratio is 1:2.
So new ratio is multiply by 2 we get 2:4 (because we want water only).
Old ratio: 2:1.
New ratio: 2:4.
-----
0:3
-----
So (3/sum of old ratio) *60=3/3*60=60 is the answer. This method can be applied to all problems like this.

@All.
It is very easy.
If a 60litres 2:1 ratio therefore 60 divided into 40,20
And next 1:2 ratio therefore 60 is divided into 20,40.
The first ratio is milk and the second one is water add the second one because we need an added quantity of water of 20 + 40 = 60l

A mixture contains milk and water in the ratio 5:1. On adding 5 litres of water, the ratio of milk to water becomes 5:2. The quantity of mil in the original mixture is
A) 16 litres B) 25 litres C) 22.75 litres D) 32.5 litres
Hey can anyone explain this for me ?

There are two types of a mixture of milk and water. In the first mixture, out of 27 LTR, 24 LTR is milk only and in the second mixture, 40 LTR is milk and 5 LTR is water. Which one mixture is
better in terms of milk's strength?
Find the solution of the problem.

in this que., it doesn't say that the new mixture's quantity is same as the before ones(60lr).Also we can't assume 60lr for the new mixture..So, as per the newmix. it's quant. is
water : 2/3 : 80 lr
milk : 1/3 : 40 lr
____________________
total: 120 lr
water : 2/3 : 80 lr
milk : 1/3 : 40 lr
____________________
total: 120 lr

The ratio is 2:1 the total mixture =60 litres let the amount of milk be 2x and amount of water be x so 2x+x =60 litres that is x=20 litres the amount milk is 40 litres.
If it is halved in the next ratio then the amount of water should be 2*40-20 = 60 litres.
If it is halved in the next ratio then the amount of water should be 2*40-20 = 60 litres.
