Thread: Average Salary

Suppose A,B,C are d 3 frnds.

Now, A 's salary -- AS
B's salary -- BS
C's salary --- CS

And A, to his salary adds a random no.(AR) and den tells dat to B.
B also adds sm random number(BR) to his salary and adds to the number whatever A has given ie. AS+AR+BS+BR. and gives to C
C also adds sm random number to his salary and adds dat to wtevr B has given him. AS+BS+CS+AR+BR+CR

Now...
A subtracts his random no. from the sum --- AS+BS+CS+BR+CR
Then B 2 vl subtract his random no. --- AS+BS+CS+CR
C 2 vl subtract -------------------- AS +BS +CS

Now,after C is done..the result is divided by 3 --- which gives the average of the salary.

From this,once d average is known..any of them cn knw d sum of d other 2 salaries

I have 2+ years of experience how much salary will take
