But when you read it carefully, the trick becomes clear. The same eggs can be involved in multiple steps. An egg has to be broken before it can be fried, and it has to be cooked before it can be eaten. So the two eggs that were broken can be the very same two eggs that were fried and then eaten. The sentence never says they were different eggs, only that “two” were involved in each action.
That means only two eggs were actually used up. You started with six, you used two, and the remaining four were never touched.
So the answer is: four eggs are left.
