Question : 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?
My Solution : Let the 3 idiots be A,B and C. First A will add some ‘x’ amount to his salary and give that final value to B. Will will add his salary plus some ‘y’ to the sum which A has given and then give the total sum to C. C will add some ‘z’ to his salary and then adds the total sum to A’s and B’s and passes back to A.
Now A will subtract ‘x’ and pass it on to B. B will subtract ‘y’ and will pass it on to C. C will subtract ‘z’ to get the sum of the salaries of A,B and C …:)
