      The question says to absorb them on the basis of about hours. They spend 19200 hours making P and 96,000 hours making Q.
      So ( 96,000 / (19,200 + 96,000) )) x 230,400 = 192,000

      (I do stress to watch out for this when I go through the example in the lecture. I do assume you are watching the lectures (because there is no point in using the notes on their own – it is in the lectures that we explain and expand on the notes))
