Puzzle: Inverted License Plates (or why Sharmila does not go for lunch with me anymore :-) )

A couple of days back, after Sharmila had returned from India, we went out for lunch. We were discussing her experiences in India when the topic went to the new restrictions of driving in New Delhi. If you were not aware, New Delhi has promulgated new rules (I am not sure if it is effective still) that stipulates that cars with odd or even number license plates can be driven on alternate days. So, one day, if cars with only even number license plates can be driven, the next day it would be for the cars with odd number license plates. This, if I am not very mistaken, is to keep the pollution under control.

As a side story, I am told that women drivers are exempt from this rule. Which prompted me to suggest to Sharmila that we lost a great business opportunity to sell “burkhas” (the head to toe garb that many Muslim ladies wear) in New Delhi. Who is going to figure out whether it is a guy or a girl driving once they put a “burkha” on 🙂

In any case, another idea came to mind then. How about those guys with license plates that are reversible? Like if I had a license plate “6666”, I can easily take out four screws and put them back on with the license plate looking “9999”. In practice, that is not possible since there are other things written on the license plate that will clearly expose the trick but that did give rise to today’s puzzle:

How many license plates can be there which when reversed (and reattached to the car) gives a legitimate alternate parity (odd becomes even, even becomes odd) license plate?

Assume the following:

  1. License plates are no more than 4 digits long
  2. A license plate cannot start with 0
  3. 0,1,6,8,9 are the digits that while reversed looks like legitimate digits
  4. There cannot be two license plates which look the same on the roads ever

Aha! intersection point upon intersection point!!

You probably recollect my blog from yesterday where I talked about running into Nancy Yates minutes before I got onto my flight to St. Louis. (see http://www.rajibroy.com/?p=9785). Guess what happened after I got down? Well, following my normal routine, I strolled towards the luggage belts to pick up my suitcase. I had barely reached the belt when the same thing happened again – I could hear a lady’s voice yelling “Rajib! Rajib!!”. I turned around – half incredulous that I would have two intersection points in a matter of a couple of hours. But there she was – Patricia Numprasong!!

Patricia and I go back some time. In fact, in the ranks of those people who have tried to keep me in line at office – like Marte, Kelly, Denise, Stefanie, Leah, Vicky and so on…, Patricia is way up their in my list who I flustered the most. There was a short period of time when I was asked to temporarily fill in the big shoes of my personal and professional friend Rob (who is now the CIO of Etihad Airways) and Patricia was entrusted to work with me. I did get to know about her family – especially her daughter who got married around that time and her son.

It was such a delight to meet Patricia after such a long time and catch up on her and her family. I also got to make a new friend – Doreen – who was with her.

This was my first flight in the new year. With these kind of perks, I can’t wait to get back on the road again….

That was biting cold

Coldest run of the season yet : 9 deg F (-9 deg C). In St. Louis. I was dressed up for the run adequately. However, the skin on the face took a solid beating. Should have packed a ski mask… But very enjoyable run out there in nature…

Sometimes, it is not bad if a lady is yelling at you!!

Sharmila is back and that can mean only one thing – I am free to travel again. First working day – Monday morning – found me at the airport even before the sun had risen. Monday morning Atlanta airport – that is a Fitbit wearer’s dream scenario – and a flyer’s nightmare. You can easily log 10,000 steps just walking to the security queue and then weaving your way eventually to the TSA agent.

The good news is that I carry a long list of phone calls to make with me. First it was the birthday phone calls to India and Asia and then my daily calls to mom and my brother. By the time I cleared security, I was already on office calls. Those office calls continued as I went down to the train station and instead of jumping on to the train, just walked from terminal to terminal. Eventually came to my gate and noticed that they had just started boarding. The Fitbit violently vibrated signaling I had reached my goal for the day already.

As is my wont, instead of getting into the plane, I just got onto another office call and kept walking around the gate till the last person had gotten in. I love being one of the last persons to board. But as I was strolling from gate to gate, I suddenly heard – what appeared to be a lady’s voice yelling – “Oh! My God! Rajib???”.

Well, “Oh! My God” followed by your name – that too by a lady, in a uncommon place – is surely going to cause some consternation to anybody. Far more so for a nondescript person as I. I swung around and what did I see?? There was a lady sitting on the floor surrounded by her luggage and smiling at me from ear to ear.

And that is how I met Nancy Yates after a loooooong time! We did business together – well, almost did business together – in a prior life and have kept up with each other thru birthday greetings and all that but I had not seen her for the longest time. The funny part is she had to spend another minute explaining to her office mates – she was on a conference call when she spotted me – the reason for her unforeseen exuberance on the phone microphone.

Anyways, she was on a call and my flight was making last calls. I did get a chance to sit down with her, chat for a few minutes, get somebody to take a picture of us, promised to have a coffee with her soon and dart to my plane.

I was the last person to board. But the memory of seeing Nancy after such a long time will last me a longer time!!!
