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 is 2:1 the total mixture =60 litres let the amount of milk be 2x and amount of water be x so 2x+x =60 litres that is x=20 litres the amount milk is 40 litres.
If it is halved in the next ratio then the amount of water should be 2*40-20 = 60 litres.
If it is halved in the next ratio then the amount of water should be 2*40-20 = 60 litres.

For water calculation of 1st ratio.
Water: 60 * 1/3=20 lit
For second ratio the water ratio will be 2/3
So water to be added: [20+(2/3) * 60]=60 lit.
That's the answer is 'D.
Water: 60 * 1/3=20 lit
For second ratio the water ratio will be 2/3
So water to be added: [20+(2/3) * 60]=60 lit.
That's the answer is 'D.

In 2nd case, why should we consider mixture as equals to 40 litre?

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.
It says 2:1=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.
