Answer:
- There are 10 bags.
- 9 of the bags have real coins, 1 bag has fakes.
- A real coin weighs 10 g, a fake coin weighs 9 g.
Take 1 coin from the first bag, 2 coins from the 2nd bag, 3 coins from the 3rd bag, 4 coins......., 5 coins............, .........10 coins.......
If there are no fakes at all, the total weight should be: 550 grams.
If the weight is 545 grams, there would be 5 fakes, and so the fake bag would be Bag 5. (because there is a 5 gram difference)
I hope this helps!
