by on December 4th, 2017

Happy Monday!

With the Winter Holidays strongly on our minds, the Avengers are relentless in their quest for the 700+ GMAT score. Make sure you join Rahul and the rest of the group on Saturday, December 9 at 1:30am EDT as they take on Work Rate questions.

In the meantime, here’s this week’s challenge problem for you to solve:

Hoses A, B, and C pump a swimming pool full of water. Hoses A and B working simultaneously can pump the pool full of water in 4 hours, and Pumps B and C working simultaneously can pump the pool full of water in 6 hours. How long does it take pump A working alone to fill the pool?

(1) All three hoses working simultaneously can fill the pool in 3 hours and 36 minutes.

(2) Hose A and Hose C working simultaneously can fill the swimming pool in twice the time it would take all three hoses together to fill the swimming pool.

A) Statement (1) BY ITSELF is sufficient to answer the question, but statement (2) by itself is not.

B) Statement (2) BY ITSELF is sufficient to answer the question, but statement (1) by itself is not.

C) Statements (1) and (2) TAKEN TOGETHER are sufficient to answer the question, even though NEITHER statement BY ITSELF is sufficient.

D) EITHER statement BY ITSELF is sufficient to answer the question.

E) Statements (1) and (2) TAKEN TOGETHER are NOT sufficient to answer the question, requiring more data pertaining to the problem.
