Question

In a vessel, there are 10 litres of alcohol. An operation is defined as taking out five litres of what is present in the vessel and adding 10 litres of pure water to it. What is the ratio of alcohol to water after two operations?

Answer 1

Answer:

The ratio of alcohol to water = 1 : 2

Step-by-step explanation:

we are given that

There are 10 L alcohol in the vessel

According to the 1st step of given operator we have to 5 L of present thing from the vessel so

After applying first step there quantity of alcohol in vessel = 10 - 5 = 5 L

According to the 2nd step of given operator we have to add 10 L of pure water in the vessel so

After applying second step

The things in the vessel = 5 L alcohol + 10 L water

Therefor in the final solution

The ratio of alcohol to water = 5 L : 10 L = 1 : 2

Thus

The ratio of alcohol to water = 1 : 2
