A dad offered to pay his son $5 for every correct answer on his math test. His son said he would pay his Dad $8 for every incorrect answer. There were 26 questions on the test and no money was exchanged.
The son got 16 questions correct and missed 10. This means he owed his Dad 10 * $8 = $80, but his Dad owed him 16 * $5 = $80, so it was a wash. Two math equations to solve it are x + y = 26 and 5x = 8y.

“Go to the market and purchase something that is large enough to fill my bedroom, but small enough to fit in your pocket. Based on what you bring I will decide which of you is wisest.”
All three sons went to the market in search of something to satisfy their father’s demands. When they returned the father gathered them in his bedroom.
The first son put down pieces of cloth that he had bought and laid them end to end across the room, but it barely covered any of the floor.

The third son showed his father what he had purchased and the father announced, “You are truly the wisest and will inherit my land.”
