What do you think this map represents? What does the red and blue color signify?

Returning from Salt Lake City. Today’s is a geometry puzzle.

In the picture below, the shaded rectangle is 4 cm by 2 cm. Can you find the radius of the circle?

To follow up on the last map puzzle….

What do you think this world map represents? Think in terms of what ties US, Burma and what I think is Liberia…

This puzzle comes after I read something my friend Shilpa Daiya had posted.

Look at the following map. Can you guess what the map is about? Can you guess what the colors stand for?

I have a friend in office who posts some amazing facts on his white board. I have always marveled at some of the crazy facts he knows. Here is one:

1. A rye plant’s root is around 400 miles (650km) long. That is just unbelievable!!!

Here are a couple that somebody else had told me.

2. A crocodile’s digestive juices are so strong that they can digest a nail !! That is why it does not matter that they cannot chew – or for that matter even move their tongue!!!

3. That thing we call “paper money”? – it is not made of paper. Most currency bills in this world are made from – get this – cotton!!! (sometimes a mix of linen and cotton)

Here is one for you to guess and then perhaps Google.

There is only one mammal in this world that cannot jump. Can you guess which one? (BTW, regardless of what that movie title would have you believe, “white men” is NOT the answer 🙂 )

After flying to San Francisco on Monday, flying back to Atlanta on Tuesday and then to DC on Wednesday, I have no doubt that I will sleep off on tomorrow’s (Thursday) early morning flight. So, I figured I might as well post the puzzle tonight and go to sleep.

Pardon the picture – I put it quickly on my iPad app. But here is how it goes.

Six coins are arranged in two rows like in the picture on the left. In three sliding moves, you have to get the circular arrangement on the right. The rules are – (*) you can slide only one coin at a time (*) you cannot “push” other coins away when you move a coin – and of course no lifting the coin off the surface either (*) here is the interesting one – when you move a coin, you have to make sure that when you leave it in its new position, it has to touch two other coins.

A teacher in a class of small kids asked them to categorize all the letters of the alphabet by a certain rule. Most students came up with the following correct answer which has three categories:

1. B

2. A, D, O, P, Q, R,

3. C, E, F, G, H, I, J, K, L, M, N, S, T, U, V, W, X, Y, Z

Can you guess what was the rule that the teacher had given?

So Nikita and I were having dinner together and asking each other puzzles. One we came up with was “How many countries can you name that starts and ends with the same letter”? Each and every one that we came up with – Albania, Algeria, Argentina, Australia, Austria… were with “A”. We could not find a single non-“A” country. Can you? (meaning country names that start and end with the same letter and it is not A)
