Question

in 64 litre of pure milk,20 litre of water is mixed and then 1/4th of the mixture is taken out when x litre of water is added again then ratio of water to that of the milk becomes 1:2 find the value of x​

Answer 1

Answer:

108

Step-by-step explanation:

now ratio is 64 : 20

for it to be 1 : 2

total water should be double the milk

i.e. water should be 128 litres

water to be added = total water needed - water already there

x= 128 - 20= 108

therefore 108 litres of water is added

Answer 2

Answer:

9 liter

Step-by-step explanation:

total mixture was 64+20=84

1/4 th taken out

remaining mixture=63liter

now the remaining mixture is in the ratio of 64:20=16:5

16+5=63

21=63

1=3

then 16=48 which is milk remaining

and 5=15 which is water remaining in the mixture.

milk should be double of water as resultant ratio of water to milk is 1:2.

then water is 48÷2=24 in the new mixture.

water added 24-15=9liter.
