Einstein’s Riddles Hard for Aspiring Geniuses

1. Riddle: What is the next number in the series: 1, 2, 4, 7, 11?

Answer: 16.

3. Riddle: You are in a room with three light switches. Each switch relates to one of three lights in a room. Each light is either on or off. You can’t see the lights from where you are, yet you can turn the switches on and off however many times as you need. How might you sort out which switch relates to which light?

Answer: lTurn two switches on for 5 minutes, then, at that point, switch one off. Go into the room and feel the bulbs. The hot one is the one that was switched off. The one that is still on is the other switch. The leftover switch relates to the excess bulb.

5. Riddle: You have 8 balls, and one of them is marginally heavier or lighter than the others. How might you find the heavier or lighter ball in just 2 weighings on an equilibrium scale?

Answer: Weigh 3 against 3. Assuming one side is heavier, weigh 2 from the heavier side against one another. On the off chance that one is heavier, it’s the heavier ball. On the off chance that they’re equivalent, the leftover ball is heavier. In the event that the first sides were equivalent, weigh 2 from one side against one another. Assuming one is heavier, it’s the heavier ball. Assuming they’re equivalent, the excess ball is lighter.
