I like to answer or try to solve it only. 😉I didn't imagine people really enjoyed solving 😉 so I stopped.. But as there seems to be real big interest in puzzles, here are two which are relatively easier. I'll try to improve the level gradually :D1. You want to send a valuable object to a friend securely. You have a box which can be fitted with multiple locks, and you have several locks and their corresponding keys. However, your friend does not have any keys to your locks, and if you send a key in an unlocked box, the key could be copied en route. How can you and your friend send the object securely?2. Four switches can be turned on or off. One is the lightswitch for the incandescent overhead light in the next room, which is initially off, but you don't know which. The other three switches do nothing. From the room with the switches in it, you can't see whether the light in the next room is turned on or off. You may flip the switches as often and as many times as you like, but once you enter the next room to check on the light, you must be able to say which switch controls the light without flipping the switches any further. (And you can't open the door without entering, either!) How can you determine which switch controls the light?chalo, chalo solve karo 😃and request SW, to start his thread of puzzles again!!
