Solution
First of all, he measure 2 times with 5 liter bottle in a container which becomes
= 5 L × 2
= 10 L
Then he pour out 3L of milk thrice, by this way he poured out total milk
= 3 L × 3
= 9 L
The milk left in the container
= 10 L - 9 L
= 1 L
Using this process the milkman gave 1 L of milk using 3 L and 5 L bottles.
