Answer: 10 : 4 : 3
Step-by-step explanation:
According to the question,
For a medicine,
Water used = 1 liter = 1000 ml
Sucrose used = 400 ml
And, Saline used = 300 ml
Thus, the ratio of water, sucrose and saline water for making a medicine,
= 1000 : 400 : 300
= 10 : 4 : 3
Which is the required simplest form of the ratio of water, sucrose and saline water.
