Video Summary

The koala started with three branches, each having 20 leaves. It ate two leaves from the third branch, leaving 18. For the first branch, suppose a few leaves eaten results in the same number being left. This number matches the number eaten from the second branch. This setup means the total leaves remaining on both branches is 20, as one whole branch worth of leaves is entirely accounted for. Therefore, between the first two branches, 20 leaves remain. Adding the 18 leaves left on the third branch gives a total sum of 38 leaves. So, the answer is 38.
