Question

Chelannur village has a milk society. Geetha and Ammini went there to buy 4 litres of milk. But the man could not find the one-litre measure. He had only a 3 litre and a 5-litre bottle with him. But he gave them exactly 4 litres of milk. Explain how he did this.

Answer 1

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.
