In my dining room I have a triangular table which has sides of 62, 37 and 24 inches.
I also have some napkins which measure 6 inches square, can you determine how many napkins I need to totally cover the table?
Hint: What is the area of a triangle? Does this help?
This table cannot exist as the longest side is longer than the two smaller sides combined.

I was recently given a new watch for my birthday.
However, as usual with my presents, it was quite useless as it loses 6 minutes every hour.
I set it using my friend's accurate watch at midnight and it now shows 10.39am.
I know that the watch stopped 21 minutes ago so what is the correct time now?

Hint: For every real hour, how many watch minutes pass?
Since the watch is losing 6 minutes every hour, for every real hour that has passed, the watch will only show 54 minutes (i.e. for every 54 clock minutes, 60 real minutes have passed)
Since the watch shows 10:39am we know:
10:39am = (10 x 60) + 39 = 639 watch minutes
for every 54 watch minutes, 60 real minutes have passed:
(639 ÷ 54) x 60 = 710 real minutes
and converting this to hours:
710 minutes = 11 hours 50 minutes
the watch stopped 21 minutes ago, so the current time is:

Hint: Do the words make sense when read another way?
Opposites reversed: big, small: open, closed: up, down.
There are a few ways of making twenty-four using just three identical digits, 8 + 8 + 8 is one way, can you find any of the others?
Hint: There is a very simple one using 2's.
22 + 2
(3 ^ 3) - 3
(3 ^ 3 = 3 to the power of 3 = 3 x 3 x 3)
4! - 4 + 4
(4! = 4 factorial = 4 x 3 x 2 x 1)
