This classic time riddle has been completely stumping people online! It looks like a straightforward math problem at first glance, but it is actually a clever test of how your mind processes information.
The riddle asks: “A doctor gives you 3 pills and says take one every 30 minutes. How long until they’re all taken?”
What makes this puzzle so tricky is our natural instinct to simply multiply the numbers we see. When reading this quickly, most people immediately multiply 3 pills by 30 minutes to get 90 minutes. That is by far the most common wrong answer!
To find the real solution, you have to think about how you actually take medication. You take the very first pill right away at the start. Then, you wait 30 minutes to take the second pill. Finally, you wait another 30 minutes to take the third and final pill.
Since you only had to wait for two 30-minute intervals after taking that very first pill, the total time is just 60 minutes.
Answer: 60 minutes.
