You have a gold bar as payment for an employee. This gold bar is the payment for 7 days of work for the employee. You have to pay the employee everyday. If you pay the entire gold bar then employee will take it and not show up for the remaining days. You are required to pay the employee at the end of the day.
You are allowed to split the bar into smaller pieces. It costs money to split the bar so lesser the number of splits the better it is for you.
How many pieces / slices you will make of the gold bar to make sure you can make the daily payments and also keep the employee for all 7 days.

Brain Teaser 5...
How many times would you weight...
Have you seen those ball bearings used in lot of places, cars for that matter? These small shiny balls may look the same but they differ in weight, density etc. Well the puzzle in not about figuring out what type of ball bearing it is. Here is the classic quality test but then you do not have all the latest tools. You have a weighing balance (the one with two bases).
There are 15 balls that look exactly the same. You cannot make out any difference but one of them is heavier. How many time(s) would you have to use this balance to find out the heavy one? Now off course it will be best to use the balance for least number of times. I will tell you why that is....once you answer this.
More coming up....
Now if there were 23 balls instead of 15 and the first measure costs $10, second costs $100, third costs $1000 and 4th onward each measure costs $10. What will be your approach?

Software developers are different...
The other day I was thinking we software engineers can solve a lot of problems. We have a sharp mind (definitely like to talk about that). I thought how many software engineers will it take to change a light bulb?
