30 cows and 28 chickens riddle

Question: There are 30 cows in a field, and 28 chickens. How many didn’t? riddle answer

Answer: The correct answer is 10

Listen closely: 30 cows, and twenty-eight chickens. Say EIGHT and ATE.

They sound the same. Therefore, it means 20 ATE chickens. 30-20=10, so 10 cows didn’t eat any chickens.
