Mind Boggling Math Puzzles: Millennium Prize Problems
Quicker Maths offers regular tips and tricks for zooming through some arithmetic problems, as well as giving us fascinating puzzles that offer some solid food for mathematical thought. But what if you were given the opportunity to earn one million dollars to solve one math problem? That's exactly the deal that the Clay Mathematics Institute in Cambridge Massachusetts has offered. And pretty much anyone can enter to win.
The Millennium Problems, as they are known, were originally seven math problems that had existed for several years and remained unsolved. Most recently, one problem--the Poincare Conjecture--was successfully solved by Dr. Grigory Perelman of St. Petersburg, Russia. Perelman worked on and solved the problem in 2002 and 2003, and was thereafter awarded the CMI one million dollar prize in 2010, although he ended up turning down the prize money.

Interesting Logical Puzzle
This one's an interesting puzzle and DOES NOT involve any MECHANICS!
There's a Bridge 2.4 km long with a load handling capacity of exactly 1 tonne and is bound to collapse if load increases by even a single gram than a tonne.
A bus, loaded fully with passengers, of weight exactly a tonne is crossing over the bridge. At exactly 3/4th of the length of the bridge a Crow comes (out of the Blue) and sits on top of the Bus.
But to everyone's surprise, the Bridge doesn't collapse and the bus crosses it safely.
Why?

Is two equals one?
Is 2 = 1?
Today, I will prove that two is equal to one (2 = 1). I will do that in more than one way. You know what you have to do? You have to point out the fallacy in the proofs.
The Fallacious Proof - 1:
Let, a = x
a+a = a+x [add a to both sides]
2a = a+x [a+a = 2a]
2a-2x = a+x-2x [subtract 2x from both sides]
2(a-x) = a+x-2x [2a-2x = 2(a-x)]
2(a-x) = a-x [x-2x = -x]

Time to solve a very interesting and logical puzzle
I have picked up this puzzle from IBM monthly challenge. I will give the exact link of the site later (for those who are interested)
Background: It's Thanksgiving, and time to stuff the turkey. But we've got a problem. The stuffing came in a cube measuring 12cm on a side. The hole in the turkey, however, will accommodate a rectangular block measuring 8cm by 8cm by 27cm. Due to time constraints (we can't miss the parade on TV) we only want to cut the stuffing into four pieces.
The question:
How can we cut the 12cm cube into four pieces which will reassemble into an 8cm by 8cm by 27cm block?

Mystery of Missing Rupee
Dear Friends,
I am presenting to you a very interesting riddle. Once you get the answer to this you can pose this riddle to your friends, etc. I am sure most of them will not be able to solve the mystery of the missing rupee.
Riddle: Mystery of Missing Rupee
Three men walk into a hotel and rent a room for Rs. 30. They contribute towards the room rent equally. So each one of the paid Rs. 10
The hotel manager after sometime realized the room rent should have been only Rs. 25 rupees. So he sent the dishonest bellboy and told him to give Rs. 5 back to the men.
The bellboy cheated and gave each one of them Re. 1 back.
Now you know Rs. 27 (10-1 = Rs. 9 each) is paid by the 3 men and Rs. 2 is with the bell boy. That makes it Rs. 29 (27+2), so where is the remaining Re.1
**This question is actually meant to be asked when you are face to face with the other person.
I think its effectiveness and punch was somewhat lost in written words. Nevertheless, give it try and enjoy asking it to others.

Here is a simple arithmetic puzzle for your
I give you 3 digits and a result and you must put all the signs necessary to restore the equality.
I give you an example. The remainder you solve by yourself.
2 + 2 + 2 = 6
Easy! Isn't this? It is the same for the remainder.
