Step 1: Tom initially has 4 apples.
Step 2: Tom gives 2 apples to his friend, so he has 4 - 2 = 2 apples left.
Step 3: Tom receives 1 apple from another friend, so he now has 2 + 1 = 3 apples.
Step 4: Tom finds 3 more apples in his backpack, so he now has 3 + 3 = 6 apples.

Final answer: Tom has 6 apples after all these events.
