It takes Joe and Ted four hours to paint a room when they work together. How long does it take Joe working by himself to paint the same room?
(1) The dimensions of the room are 12' by 12' by 8'.
(2) It takes Ted seven hours to paint the room by himself.
The OA is option B.
I know that statement (1) is not sufficient, but how can I use statement (2) to get a conclusion? Experts, can you give me some help?
