I am convinced about E and I also know the answer is B. I think B is a naive choice with no life and assumes the least resistant of the numbers which is 1,9,20. If we chose 5,9,24 then the mean would be 12.66. If the question stem would have said, which of the following is a posible mean, then I think B is the right answer. Else E suits me best. Alternately the choice E should not have been there - because it triggers the potential trick. But when we know its B, I feel this to the guy who wrote this question -

I don't understand how it can be different than E ?
The numbers could be: 1,9,20...
But they could also be : 9,9,9...

Dookie,
It cant be 9,9,9 because, the range is 19.

As i understand it : "the largest possible range of the three numbers is 19".
Which means no more than 19.
It doesn't mean that the range is 19. It could be less.

Agree with E and Dookie's mention which makes the problem even worse. Badly written question I guess

"Largest possible" refers that the within the set the largest range is 19, it's possible means it does exist else it would be impossible  . Hence the set must have that range as well.Still an E is the only choice.

Yep, that is why I choose E, but was furious to find that OA is B.
Surprised to see substandard questions from a big company like Princeton.
