**Solution**Let us say that the three people are A, B and C respectively. Now you, A will tell the sum of your salary and a random number to B.

SA (Actual Salary) + A (random number of A)

In the same manner your friend B, will add his salary with a random number to the amount given by A (you) and will pass it to C.

(SA + A) + (SB + B)

C will do the same.

(SA + A) + (SB + B) + (SC + C)

Now C will pass this total amount to A. He will subtract his random number from the amount and it will become:

(SA) + (SB + B) + (SC + C)

Then he will pass it to B and B will subtract his random number from the amount.

(SA) + (SB) + (SC + C)

Then he will pass this to C who will subtract his random number.

(SA) + (SB) + (SC)

Now C has the total amount of their combined salaries. He will tell the amount to all of you and you can easily divide it by 3 to get the average salary.
