You are given one 3 litre container and one 5 litre container.
How to use this two containers to measure 4 litre water accurately and what is it minimum step to achieve it.
Note: There is no any label on the container and it is impossible for you to obtain 1.5 litre water in half full 3 litre container. It is because all of them are in strange shape.
ANSWER:
3 steps only.
1. Fill-in 3 litre container full then drop this 3 litre water in the 5 litre container.
2. Repeat it but there will remain exactly 1 litre water in the 3 litre container when the 5 litre container is full.
3. Empty the 5 litre container and drop the remainder 1 litre into it follow by 1 full 3 litre water.
This is one of the tough interview questions which I have found. It will basically test your logic thinking and lateral thinking skills via mathematic approach. The question is:
