A basket full of eggs. If you put the eggs in boxes of 3 there is 1 egg left behind. If you put them on groups of 4 there is 1 egg left behind. In groups of 5 or 6 there is also 1 egg left behind. If you put them in boxes of 7 eggs they will fill them all perfectly.

QUESTION> How many eggs do we have in the basket?


And old man and his apprentice are watching the sunset when exactly 100 seagulls pass flying. They hunt one and the next day there are 99... they hunt another one.

The old man asks the young boy: "After we've hunted them all down, how many seagulls did we watch flying?

During a recent census, a man told the census taker that he had three children. When asked their ages, he replied, "The product of their ages is 72. The sum of their ages is the same as my house number." The census taker ran to the man's front door and looked at the house number. "I still can't tell," she complained. The man replied, "Oh that's right, I forgot to tell you that the oldest one likes chocolate pudding." The census taker then promptly wrote down the ages of the three children. How old are they?

Answer: The three kids are 3, 3, and 8 years old.

Explanation: As Reddit users TT1103 and RedditRage explained, the key to this brain teaser is that the census taker looks at the house number. In other words, she knows the sum of the children's ages.

However, at that point of the riddle, she still can't tell how old the man's children are. Therefore, she has to be stuck between multiple possibilities. To narrow it down further, only two sets of numbers that multiply to 72 share the same sum: (2,6,6) and (3,3,8).

After the man reveals that his oldest child likes chocolate pudding, however, the census taker can differentiate between the two options. That is, only the latter of those two sets has a distinct "oldest" child.
