The Baseball Conundrum

The Baseball Conundrum

Here is a brain teaser that has taken several forms in the past, but I remember it as a baseball-themed enigma. Think about it carefully. You may think that your answer is a logical deduction, but it may very well be wrong. Also, if you do come across a store that charges such high prices, you may want to consider shopping elsewhere! So, anyway, the problem is:

If a baseball and baseball bat cost $110, and the baseball bat costs $100 more than the baseball, how much does the baseball cost?

The answer and explanation are below, but if you want a hint as to how to solve this puzzle, try to use a little bit of algebra in your reasoning – and try to solve it by using pen and paper!

Answer and Explanation

The cost of the baseball is $5.00.

How did I solve this problem?  I wrote it out so that I can visually see what is going on (I can’t see it in my mind very well because it is clouded with such unsavory thoughts!):

ball + bat = 110

bat = 100 + ball

by substitution:

ball + 100 + ball = 110

Rearranging:

ball + ball + 100 = 110

2 balls + 100 = 110

2 balls = 110 – 100

2 balls = 10

And so:

1 ball = $5

So the real question here is, what is so special about the bat that would justify a price of $105?!!
