Question of GRE®?

[Wilsonmcw]

Hi friends,

I am going to face a test with the some questions related to the below format. However, I cannot find any material containing such type of question for my preparation, including GMAT!!!

Can anybody tell me whether the below type of question is related to Data Analysis?

Where I can find the materials for practice (website or books)? (I can't find any material related to those question so far)

Thanks a lot!

Sample question
Ada, Mary, April and Joanna participated in a charity walkathon. The fastest walker returned to the finishing point in 35 minutes. Which TWO pieces of information can tell you who was the fastest walker?

(1) Ada finished the walkathon in 41 minutes.
(2) April finished the walkathon earlier than Mary by 2 minutes.
(3) Mary finished the walkathon later than Joanna by 4 minutes.
(4) Joanna finished the walkathon earlier than Ada by 6 minutes.
(5) Ada finished the walkathon later than April by 4 minutes.

A. (1) and (2)
B. (1) and (4)
C. (2) and (3)
D. (2) and (5)
E. (3) and (4)

(Answer: The winner finished the walkathon in 35 minutes. Statements (1) and (4), when taken together, tell that Joanna can finish in 35 minutes. Therefore, the correct answer is B.)
