Wow, the riddles
The riddles were my favorite part :]
1] The month one: every month has at LEAST 28 days in it .
2] Half of 20 riddle: the answer is 15.
1/3 of 6 = 3 and 1/2 of 20= ?
and actually 1/3 of 6 =2 and 1/2 of 20=10
so 2=3 and 10=?
so by cross multiplying 10*3/2=30/2=15
so 15 is the answer
3] Gem riddle:
33" is the answer.
Some people mix up the question. He doesn't mean ensure that just drawing twice will get you two different gems. He means after drawing so many times when are you absolutely sure you'll have two different gems within the pile you've taken out.
