Answer:
No, the output is not possible
Explanation:
The first guy was wrong. Even though they could have 1 nail painted each, the question says a full rack of nails (10). So the output cannot be 20 and has to be 200 because 20x10=200.
Well, I think yes.
Why? Well if they saw 20 people and painted 1 nail on each of the people then it could be true... Correct me if I am wrong.
