This money puzzle is simple once you follow the instructions one step at a time: You have $900. Remove $300, then remove half of what is left. How much do you have?
The answer is $300.
Start with $900 and remove $300. That leaves $600. Next, the puzzle says to remove half of what is left. Half of $600 is $300. Removing that $300 leaves another $300.
The key is that the word “half” refers to the amount remaining after the first subtraction, not half of the original $900. Reading the sequence carefully avoids the trap.
So: $900 − $300 = $600, and $600 − $300 = $300. Did you get the same result?
