Answer:
d.25:11
Step-by-step explanation:
25/(25+11)=(1-(4/k))^2
25/36=(1-(4/k))^2
(5/6)^2=(1-(4/k))^2
5/6=1-4/k
4/k=1-5/6
4/k=1/6
k=4*6
k=24 lit.

Answer:
Step-by-step explanation:
Answer:25:11
Step-by-step explanation:
volume of milk left=initial volume of milk(1-x/v)^n
initial volume of milk=24 litres=volume of vessel
x=4 litres ; n=2 times
volume of milk left =24(1-(4/24))^2
=50/3
ratio of milk to water =(50/3)/(24-(50/3))
=50/22
= 25/11
