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:
20 litres
30 litres
40 litres
60 litres
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.

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.

First ratio:-2:1.
Milk qunts 1/2*60=30,
Water qunts 60-30=30,

New ratio:-1:2
ratio quantity doubled,
2*30=60lts.

The simple trick is;

60litres mixture ratio 2:1 then 40:20.
In question, water is added to the mixture so milk quantity doesn't change. New ratio 1:2 milk same i.e 40 then 2*40= 80 (water ratio 2) old is 40:20 new is 40:80 (80-20)= 60ans.

very simple way.

The ratio of milk and water :: 2:1
Total mixture of milk and water =60 lits
milk =2x
water=1x

=> lit of milk+lit of water=total lits.
=>2x+1x=60,
=>3x=60,
=>x=20.
