# Salary of each other riddle

Three coworkers would like to know their average salary. However, they are self-conscious and don’t want to tell each other their own salaries, for fear of either being ridiculed or getting their houses robbed. How can they find their average salary, without disclosing their own salaries?

* Well since all three members are out for a brisk walk…they could find some random guy and tell their salary individually and ask him to calculate the average , which will be an easy task but if this option is not available then,

* Member 1 will add a random number to his salary and tells the sum to Member 2

Member 2 will again add a new random number to the number provided by Member 1 and share it with member 3

and further Member 3 will add another random number and say it to member 1

Now member 1 will subtract his random number from the total sum provided by Member 3 and member 2 will do the same ….and continude by member 3…

So now you have the their total salaries …divide by 3 to find the avg.
