I got this puzzle from my brother-in-law today (all your jokes about troubles created by inlaws to be inserted here 🙂 ). I believe I have arrived at the right answer but since he does not know the answer himself, would like to see if others can prove or disprove me.
A car’s wear and tear pattern is such that any new tire put in the front can last 40,000 miles and the ones in the rear can last 60,000 miles. You are given four new tires to begin with and you can interchange the tires between front and rear as many times as you want. What is the maximum distance you can drive?
Strictly speaking, it is not puzzle time since I am flying out of Atlanta not to Atlanta. But what the hell, it is holiday season… so, here goes..
I was addressing a large audience this morning and asked those who have two kids to raise their hands. Then I asked – of all the people who have their hands raised – to keep their hands raised if one of their child is a son born on a Sunday. They rest can put their hands down. Now I picked any one from the ones left with their hands raised. What is the probability that their other child is a son?
(assume equal probability for having a son or a daughter or which day of the week a child is born).
Most consider my travel schedule to be crazy. I admit it can be onerous. But the upsides are huge. If I am not learning about local politics and history, I get to meet people who have touched my life in the past. Today, in the middle of all sorts of meetings (talk about something being onerous 🙂 ), Rishi Bandopadhay arranged to come and have a quick lunch with me. I met him first in 1994 when he was barely a year old. Was a role model for a lot of kids in Dallas including my daughters. Today he is in NYU. Thank you Gampu for hunting me down and then taking time off from your year end test preparations to have lunch with me. That was special!!! Sorry I could not spend more time what with all the client meetings…
Here is a small experience that inspired me about values. As I was boarding the flight to NY last night, I was chatting up the flight attendant who has been with Delta for over 25 years. I asked her about an interesting event she experienced. She talked about how just the previous day, the CEO of Delta was in her flight. She regretted she could not serve him because she takes care of first class and he with his office people were sitting waaaaay back in economy. I called up one of his direct reports who I happened to know professionally and he confirmed that the CEO travels economy in his own airline for business!!!
I recognize there are different styles to succeed but this story somehow spoke to me!
