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.

@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.

The ratio of milk to water is given as: 2:1.
Let us assume a quantity of milk is 2x ans water is x.
Therefore ,
2x + x = 60 liters (Total mixture).
3x = 60
x = 20 --------(1)
Now milk is 2x therefore 2*20 = 40 liters is milk.
Now new water is added therefore x becomes (20 + x),
now new ration is given 40 /(20+x) = 1/2,
80 = 20 + x.
x = 60 Liters.

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.

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.

60 lit, 2:1.
2x +1x = 60 lit,
3x = 60,
x = 60/3,
x = 20 lit.
2x +1x = 60 lit,
3x = 60,
x = 60/3,
x = 20 lit.

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.

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.

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

I DON UNDERSTAND..IN 2:1 RATIO MILK IS 40L AND WATER IS 20L..IN 1:2 RATIO,YOU CAN JUST SAY AS MILK 20L AND WATER 40L NO?IF SO,THE WATER THAT IS TO BE ADDED FURTHER FROM THE PREVIOUS MIXTURE TO MAKE IT TO 40L IS JUST 20L NO..?WHY TO DO SUCH CALCULATIONS??
