Answer:25 parts of water to be added in 5 parts of powder .
Step-by-step explanation:
The ratio of powder to water required for a medicine is 1:5
If we have 5 parts of powder
To find : Parts of water to be added
Let x be the parts of water added when there is 5 parts of powder
Therefore we have
Powder 1 5
Water 5 x
Clearly, it is in direct variation
So we have
[tex]\dfrac{1}{5}=\dfrac{5}{x}\\\\\Rightarrow x= 5\times 5 = 25[/tex]
Hence, 25 parts of water to be added in 5 parts of powder.
