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.

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.

M:W (initial mixture)
2:1
1:2(required).
Given total volume = 60ltrs.
As milk is not added we the ratio of milk need to be same in both the cases.
2*(1:2)=2:4(required).
2:1(initial).
4-1=3(difference in water in both cases).
2+1=total volume (60).
3-----> 60.
From this, we can say another 3 parts were added to get the required ratio.

Milk:Water = 40:20 = 2:1.
But we don't change milk we want to add water to change the ratio so 1:2 = 40:80 already 20liter is there so if we add 60ltr the ratio will come that's all.

2:1 = 40+20 = 60.
New Ratio 1:2 = 20+40 = 60.
Answer 60.
New Ratio 1:2 = 20+40 = 60.
Answer 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.
