I'm stuck on #28 and #30:
http://www.keepmebusy.com/link.php?id=2013 You have to figure out what the abbreviation is for (24 H in a D = 24 hours in a day)
28) 23 P of C in the H B
I keep thinking that HB is holy bible, which might mean that P is psalms, but there's more than 23 of them. Is the C Christ? Or is this not religion related at all?
30) 9 P in S A
There's 9 planets in the solar system, but that doesn't fit the format... 9 pence in sterling A?
Are these both sports related? I figured out the other sports ones...
