If it takes Patrick 4 hours . . .

    If it takes Patrick 4 hours to paint a room, how long did it take Patrick and Roger working together?

    (1) Roger started painting the room at 12 noon.
    (2) It takes Roger 3 hours to paint the room.

    B is the Official Answer.

    The statement (1) is not sufficient? Why not?

    Hi Vincen,

    We need rates of painting of Patrick and Roger to get their combined rate.

    Statement 1 itself is not sufficient since we do not know after starting at 12, by what time Roger completed the work. Thus, the rate of Roger is not known.

    Hope this helps!
