Money For Answers

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.

How did this happen?

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.

Find The Hidden Cities

Wallace died a wealthy, if somewhat odd, man without any living relatives. He left his money in four different cities for the first four people who could find it. The only clue he left was this poem:

Do not go solo,
Pairs up with a friend,
Though I hasten to add,
I’ll avenge my end.

What are the four cities?

Anagrams of four cities can be found in the poem.

Oslo (solo)
Paris (pairs)
Athens (hasten)
Geneva (avenge)

My First Wears My Second

My first wears my second; my third might be
What my first would acquire if he went to the sea.
Put together my one, two, three
And the belle of New York is the girl for me.

Manhattan. A MAN wears a HAT, and a MAN might acquire a TAN if he went to sea.

The Long River

How many times does the letter S appear in the name of the longest river in the world?

Zero. The Nile is the longest river in the world. Some claim the Amazon as the longest, but that too has no “S”es (that looks weird but I don’t know how else to write the plural of “s”). The Mississippi is the 4th largest river in the world according to a href=”https://en.wikipedia.org/wiki/List_of_rivers_by_length”>Wikipedia.
