Challenge: Find the faked coin

There’re 11 coins which are identical looking. Knowing that there’s one faked coin with different weight within the real ones. All real coins are the same weight. Using a balanced scale, can you find the faked coin with only no more than 3 times weighting?

Have fun! 🙂
