# Ten Fun Reasoning Questions: Challenge Your Logical Mind!

1.In a room, there are three switches, each controlling a different light bulb. You can only enter the room once. How can you determine which switch controls which light bulb?

Correct Answer:Turn on one switch, wait for a while, then turn it off. Turn on another switch, then immediately enter the room. The bulb that is on corresponds to the second switch, the warm bulb corresponds to the first switch, and the remaining bulb corresponds to the third switch.

2.In a bag, there are three red balls and three blue balls. Without looking, how many times do you need to pick a ball to ensure you get two of the same color?
