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.

Mixture = 60 litre
ratio is 2: 1 , so milk:water=40:20
New ration= 1: 2 , means milk : water should be 40:80
Water in the new mixture should be 80
Less water already in the mix 20
Water to be added now is 60
ratio is 2: 1 , so milk:water=40:20
New ration= 1: 2 , means milk : water should be 40:80
Water in the new mixture should be 80
Less water already in the mix 20
Water to be added now is 60

The answer is simple, when the ratio is 2:1 than quantity is 40 liters:20 liters and when it has to be made 1:2, then at 60 liter water. So the quantity of milk remains 40 liters and water is increases to 80 liters.

2x+x=60 => x=20,
So Milk=40L and Water=20L ,
Now to make 1:2 i.e. Milk=x and Water=2x.
We already have Milk=40L and we can take it as x=40 and Water as 2x=2*40=80L.
So, Water to be added is 80-20=60L (ans).
So Milk=40L and Water=20L ,
Now to make 1:2 i.e. Milk=x and Water=2x.
We already have Milk=40L and we can take it as x=40 and Water as 2x=2*40=80L.
So, Water to be added is 80-20=60L (ans).

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.

Am saying just simple formula for this.
If an x liters mixture of milk & water the ratio of milk of water is a:b.
The quantity of water to be added in order to make this ratio c:d is x(ad-bc)/c(a+b).
If an x liters mixture of milk & water the ratio of milk of water is a:b.
The quantity of water to be added in order to make this ratio c:d is x(ad-bc)/c(a+b).

Just make it simple.
If the quantity of milk remains same 40.
And the new ratio is 1:2.
It means water is double then milk according to ratio then we have 40:80. And, minus the old water means 80-20 = 60.

Mixture of milk and water is = 60 liters that is milk:water.
As per given ratio is = 1:2 that is 40:20.
As per asking ratio is = 2:1 that is 20:40.
Further added milk & water = 3:3 that is 60:60.

25 chairs cost as much as 42stools 35 costs as much as 18 tables 10 tables costs as much as 12 benches and a pair of benches costs 625 find the cost of 1 chair.
Can anyone answer for this question?

Total Mixture 60 liter and ration of the milk and water is 2:1.
Then milk is 40 lit and water is 20 lit.
If you go options 40 has to be correct ?
40 : 20 => 40: 20+60 => 40: 80 => 1:2.
Then milk is 40 lit and water is 20 lit.
If you go options 40 has to be correct ?
40 : 20 => 40: 20+60 => 40: 80 => 1:2.

Actually, I think we don't need to find the solution for this question so hard.
It says 2:1=60.
So, if its interchange to 1:2 answer is also 60 ltr since the two products do not change changed.
