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 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.

By Using the relation,
X(ad-bc)/c(a+b)
We get,
= 60(2×2-1×1)/1(2+1),
= 60(4-1)/3,
= 60.
X(ad-bc)/c(a+b)
We get,
= 60(2×2-1×1)/1(2+1),
= 60(4-1)/3,
= 60.

Here 2:1 and then 1:2 at first find the difference 2-1 = 1 and 1-2 is also 1 deference,
So, we say 1 unit = 60L.
The question is whether water should be added further?
Hence, the water ratio is 1, so the answer is 1*60 = 60.
So, we say 1 unit = 60L.
The question is whether water should be added further?
Hence, the water ratio is 1, so the answer is 1*60 = 60.

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

First, the ratio is 2:1 is 40: 20,
New ratio is 1: 2 is 20:40.
We want the water so we can add water such that 20+40=60.
New ratio is 1: 2 is 20:40.
We want the water so we can add water such that 20+40=60.
