Think you can crack these? 👀 RIDDLE 1: The Bridge 🌉 4 people need to cross a bridge at night. They have only 1 torch, and only 2 people can cross at a time. Their crossing times are: A → 1 min B → 2 min C → 7 min D → 10 min When two people cross together, they move at the slower person’s speed. 👉 What is the minimum time needed to get everyone across? RIDDLE 2: The Poisoned Bottle 🐀 You have 4 bottles: A, B, C and D. One contains poison, while the other three contain normal milk. You have 1 rat. If the rat drinks the poison, it dies exactly 10 hours later. You also have a watch that tells you how many whole hours are left, but not the exact current time. 👉 What strategy would you use to identify the poisoned bottle? RIDDLE 3: The Three Switches 💡 You’re in a room with 3 switches. Each switch is connected to one of 3 bulbs in another room. You cannot see the bulbs from where you are. You can switch them on or off however you want, but you can enter the bulb room only once. 👉 How will you figure out which switch controls which bulb? RIDDLE 4: The Two Ropes 🔥 You have 2 ropes. Each rope takes exactly 60 minutes to completely burn, but they do not burn at a uniform speed. You have a lighter. 👉 How can you measure exactly 45 minutes? Think you can solve all 4? 👀 Try them before looking for the answers. Comment “YES” and I’ll share the answers. 🧠
