5th graders in Shuqing, China received a math paper with an apparently unsolveable math question.

The question that was asked is

"If a ship had 26 sheep and 10 goats onboard, how old is the ship's captain?"

Many people have offered possible guesses as to what the answer might be, while some thought this was a joke.
However, education officials in China confirmed this is indeed a real question.
