A man and a boy together dig 600 kg of earth in an hour (600 kg/hr) working independently but simultaneously. How long would the man take working alone?
(1) The man moves twice as much earth as the boy
(2) The boy works 3 hours by himself
A. 1 alone, not 2 alone
B. 2 alone, not 1 alone
C. 1 and 2 together (need both) Answer
D. 1 alone or 2 alone
E. 1 and 2 together are not sufficient
According to the source (How to pass the GMAT-unbeatable preparation for success...) the right answer is D.
According the me the right answer should be A, because the fact that the boy works 3 hours by himself does't give me any information relevant to the question.
Of course if they have told us, that the boy needs 3 hours to dig 600 kg by himself, it would habe been answer D, but this is not mentioned.

If all questions in that source have the same awful wording I wouldn't study it all. By the way you are right about (2).

it is a book called "How to pass the GMAT- Unbeatable preparation for success in the GMAt" by Mike Bryon and this was a question from one of the 6 full-lenght "realistic" timed tests. If it's really not a reliable source, I would then leave it.
Thanks for the immediate responce!
