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.

I can't understand this question. Can anybody tell me this question in very simple way?

(m1*w1)/L1 = (m2*w2)/L2.
(2*1)/60 = (1*2)/L2.
2/60 = 2/L2.
2L2 = 120.
L2 = 60.
(2*1)/60 = (1*2)/L2.
2/60 = 2/L2.
2L2 = 120.
L2 = 60.

It's confusing please someone explain me to get the method of solving the problem.

Simple formula is X(ad-bc)/c(a+b).
Applying this.
60(4-1)/1(2+1),
60*3/3= 60 ltr.
Applying this.
60(4-1)/1(2+1),
60*3/3= 60 ltr.

m-2:1-w.
m-1:2-w.
2:1 4-1=3 difference by addition of water,
2:4
3 * 60/3 = 60.
m-1:2-w.
2:1 4-1=3 difference by addition of water,
2:4
3 * 60/3 = 60.

Why have you multiplied 60 (2/3) for quantity of milk? where did the 3 come from?
Ruchi said:

2/3 we can obtain from formula here a:b is 2:1.
then the formula is use a/(a+b)
then the formula is use a/(a+b)
Biseswar said:

Formula = x(a*d-b*c)/c(a+b).
The required water = 60(2*2-1*1)/1(2+1) = 60 lit.
The required water = 60(2*2-1*1)/1(2+1) = 60 lit.
