Why do you need to remember the value of 1/7? Can't you calculate 11/7 to 5 decimal places in 10 secs?
Hi Ash, the fact is that it was not the "smart way" to do the division like we all know. If you know the value of 1/7 and notice that 11/7 is 10*1/7 + 1/7 then it's not 10 seconds you need but 2. I was actually stopped after the third decimal. It seems 1/7 is a value to know like 1/8 and so on. Cheers. Paul.
Hi Paul, Thanks a lot for getting back to me. Now I understand what you meant. By the way, wouldn't it take much more time in adding 1.42857... and 0.142857... than calculating the value directly? I have face-to-face interviews later in this month. Your post was really detailed and I can't thank you enough for that. I have few doubts though: 1. 25 horse puzzle: was it how many number of races would it take to find the top 3 fastest horses given you can race max 5 at a time? 2. Do you remember any other brainteasers? 3. Didn't they ask any Options n Greeks question in the face to face tech interview? Would you like to give any other advice or tips? Cheers! Ash
