Can somebody help me with this simple math problem?

I thought it to be a fairly simple problem. Now I am stuck. I was reading a book that talked about organizational efficiency. It talked about 3 parameters. Each parameters can take the value of 1 thru 10. So, there are 1000 combinations.

It is at this point, I got totally distracted. The quick thought that came to me mind was how many different products can I get? And ever since, the book be darned, I cannot get my mind off it.

So, to repeat, there are three spots. You can fill each one of them with a number 1-10. So, you get 1000 possibilities. If you take the product of those 1000 possibilities, you will get 1000 numbers. But there will be repeats. For example,(1,2,3) (1,3,2) (2,3,1) (2,1,3) (3,2,1) (3,1,2) (1,1,6) (1,6,1) (6,1,1) will all give 6 as the product.

How many distinct products can you have?

I should never be let loose in an airport which has a great fountain pen shop in it

… or for that matter, any fountain pen shop!!

I remember making friends with Karan Dhir in the William Penn store in Terminal 1 in Mumbai airport a few years back. The gentleman clearly was one of the rare people in today’s world who understand fountain pens. I remember buying one that day and then he presented me another!

Today, while in Terminal 2, I saw another William Penn store. I was hoping to see Karan there. Unfortunately, he is still in Terminal 1 (and in Mumbai, there is no easy way to go from Terminal 2 to Terminal 1). I did make friends with Kiran here and landed up picking three fountain pens.

Loved the coffee color pen. Goes with my fondness for everything coffee lately. Also, got my first Sailor pen. I was a bit worried about the Medium tip nib till Karan pointed out that it is a Japanese company. Japanese pens tend to be half to a full point thinner in nib edge for the same classification (of nib edges) and I love the tactile feedback of fine tips.

Can’t wait to go home, put some ink and start writing with these!

Vexillology quiz

These days, I have found a great way to learn more about country flags. My friend in office – Danny – is a wizard at this. He asks me questions. I get stumped and then I learn. I come home and learn a few more countries and go back and ask him next day. He answers them without even blinking. My upside is that in the process, I am learning!!

There is another friend of mine Sharmistha – in Houston – who is equally adept in world flags!

Someday, I am going to be like them. Right now I am grinding thru it – one flag at a time…

Here are some interesting things I have learnt…

1. Most all flags are rectangles. However, 2 countries have square flags. Can you name them?

2. Here might be something most people know. Which country has a flag that is neither rectangle nor square?

3. What is the most common color in all the country flags? It is found in a whopping 75%+ flags!

4. What is the most rare color in country flags? How many countries have them?

5. Which country has had the most number of flags?

6. What was the least amount of time that a country flag survived before it was substituted?

7. Which country has the oldest continuously used flag? Celebrating 400 years this year, in fact!

8. How many countries have the front side and the reverse side of the flag different from each other?

9. In the 1936 Summer Olympics, two countries showed up to compete and realized they have the same flag! Next year one of them made an alteration to their flag. Which two countries were these?

10. Many countries have images of arms – often symbolising their struggle and sacrifice for independence. Saudi Arabia’s for example, has a sword. But there is one country that has a AK-47 on its flag!! Can you name it?
