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.

The ratio of milk and water in 60L is;
m=2.
w=1 (2+1)=3,
milk = 2/3, water=1/3.
milk in 60L = 2/3 * 60= 40L.
water in 60L = 1/3 * 60= 20L,
40:(20+60)=4:8= 1:2.
m=2.
w=1 (2+1)=3,
milk = 2/3, water=1/3.
milk in 60L = 2/3 * 60= 40L.
water in 60L = 1/3 * 60= 20L,
40:(20+60)=4:8= 1:2.

@All.
Simply the solution is;
Mixture = 60 litre.
The ratio is 2: 1 , so milk:water=40:20.
New ratio= 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.

m:w=2:1
m+w=60
2x+x-=60
x=20.
m=40 w=20.
Added water be y.
40:(20+y) = 1:2.
On cross multiplication
y=60.
m+w=60
2x+x-=60
x=20.
m=40 w=20.
Added water be y.
40:(20+y) = 1:2.
On cross multiplication
y=60.

The initial quantity of milk=(2/3)*90 = 60,
Initial quantity of water=(1/3)*90 = 30,
If the ratio is to be 2:3 the water to be added;
(60÷(30+x)) = 2/3,
X = 60.
Initial quantity of water=(1/3)*90 = 30,
If the ratio is to be 2:3 the water to be added;
(60÷(30+x)) = 2/3,
X = 60.

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

Total = 60.
Milk: water 2:1 means 40:20.
60*40/20 = 120.
1:2 new ratio, then water added
120 = 40:80.
Then,
120*40/80 = 60.
Thank you.

Initially we have 60lt in the ratio 2:1.
i.e: 40lt milk & 20lt water.
Think logically,
Our condition is to make the ratio as 1:2.
i.e: 40lt milk & 80lt water.
Then 40 : 80 it will become 1:2.
So, the required amount of water will be 80 - 20 (i.e: final quantity - initial quantity -> then we can get req amount of water to make the ratio as 1:2).
i.e: 40lt milk & 20lt water.

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.
