Solution may be wrong (Question:218816.0)

Because, according to problem, if x is the average when first person steps on the weighing machine then for the second person, the average should be x+1, similarly after third person it should be x+2. but according to your solution the average weight becomes 3x+5 divided by 3 which is not satisfying the question.
Instead the weights will be x, x+2, x+4, x+6 and x+8. then the equation satisfies and the answer will be 8.
