This is how I got my answer:
Between 08:00 and 12:00 noon, there are 240 minutes.
Divide it into 6 segments to get 40 minutes.
At 11:20, it is 200 minutes after 08:00 and 40 minutes before 12:00, i.e. 5 times as many bla bla bla.
But that happened 84 minutes ago.
Therefore it is now 12:44, i.e. 84 minutes after the time when it was 5 times bla bla bla.
Therefore the question was inaccurate in saying it's "before" 12:00 noon.
I reckon tara20 was wrong to subtract the 84 minutes before divideing by 6.
