Hi,

A new brain teaser!

Imagine there are four employees seated for their dinner. Each employee is not aware of the others salaries. And our aim is to find the average salary of all four. And obviously they cant let others know about their salary. So come up with a strategy, by which they can find their average salary without knowing others salary.

Step 1:

Employee 1 adds a random number (of the same order of magnitude as the salary) and whispers the number to Employee 2.

Step 2

Employee 2 adds his/her salary and whispers the sum to Employee 3.

Step 3:

Employee 3 repeats step 2 and whispers to Employee 4

Step 4:

Employee 4 repeats step 2 but whispers the sum to Employee 1

Step 5: Employee 1 now subtracts the random number added and divides the sum by 4

Bingo.. u r right.. and there is one more solution to this problem.. try it if interested.. if not try some other question 🙂
