A mensa test

Give these a try and see how many you can get... I'll give you the first one just so you can see what it's all about....
24 H in a D - 24 Hours in a Day.
Got it? Apparently if you get 23 or more of these you are a genius! That's the theory anyway... Anyway, give it a whirl and see how you do - if you get stuck let me know. I got 29 by the way....
