DIY Challenge 1

There are 5 containers of with 5 coins each. All containers have coins of weight 5gm, expect one fake container, which has all coins of only 2gm.

Jerry is trying to find a strategy to find the fake container. She took 1 coin from the 1st container, 2 coins from the 2nd one, 3 from the 3rd….and so on.

She then placed all these coins on a digital weighing scale.

What is the possible weight she might see on the weighing scale?
