4. 99, this is 9x9x9x9x9x9x9x9x9 or 387,420,489.
**NOTE: We get lots of mail on this question and for some time we accepted that using factorials with the two digits would also be a solution for this one. However, as one of our visitors recently pointed out, that allows the use of the infinity sign as well. So we now ask the question emphasizing that only 2 digits are used in this riddle and answer. Therefore our original answer stands. HOWEVER, many visitors have suggested that the 2 digits refers to 2 fingers on your hand (fingers=digits) and that said, well, then you could write just about anything using symbols, etc. - big, big numbers!! Thanks everyone for your input!!
**NOTE: there is indeed another solution for this riddle: There is another solution if you follow your current wording to the letter. You dont mention that you may not repeatedly use the 2 digits you choose. The definition of a digit is :-"One of the elements that collectively form a system of numbers" Any single integer in our regular base10 numerical system is therefore a digit (0 through 9). But 100001 is a number made from 2 digits and 2 digits only, nothing else. Its just the digit 1 is repeated twice and 0 is repeated 4 times. If you discount the use of the infinity sign (which is technically a digit of base10 but ruins the answer) then the my answer is 1 followed by as many 0s as you can possibly write (an infinite number of 0s) - since this will always be two more than as many 9s as you can ever write with an 8 on the end (to preserve the 2 digit rule!).
NB - You can also argue this the other way round i suppose - that if youve just written 1 and as many 0s as you possibly can, someone else could come along and write as many 9s as that and stick an 8 on the end for good measure.....the infinite paradox rears its head again!
A bit pedantic i know but as that's the point of these riddles i just thought id point it out!
5. Mount Everest has always been the tallest mountain, even before being discovered!
*NOTE: Here is an interesting rebuttal on this answer: Everyone knows that Mount Everest is the tallest mountain in the world, right? Well, if you want to get technical about it, the answer is NO. Mount Everest stands 29,028 feet tall. From top to bottom, it's taller than any other mountain-whose bottom is the surface of the earth. Here's the catch: If you add what's underneath, then Mount Everest isn't the tallest mountain. The winner then is Mauna Kea, a huge, very tall volcano on the Big Island of Hawaii (called Hawaii). Mauna Kea stretches 13,796 above water and 19,680 underwater, for a total of 33,476! So if you say that it's the whole mountain that counts, then Mauna Kea is the tallest.
Another argument is that; Mount Chimborazo in the Andes of Ecuador. Mount Chimborazo is the tallest mountain from the center of the earth. Since Mount Chimborazo is on the equator, it is boosted much higher from the core. In terms of from sea level, Mount Everest is 8,848 meters and Mount Chimborazo is only 6,267 meters. But in terms of from the core of the earth, Mount Chimborazo is 6,384,404 meters and Mount Everest is only 6,381,670. This makes the peak of Mount Chimborazo 2,734 meters higher than the peak of Mount Everest. I believe that this should at least be mentioned in the answer or as a note.
6. 6, he makes 5 originals from the 25 butts he found, and after he smokes them he has 5 butts left for another cigar.
7. The Sequoia. She only likes words with all 5 vowels in them. The Sequoia is the only American tree that contains all 5 vowels.
Also, the Sequoia is not the only North American tree with all five vowels. The Southern Magnolia, Quaking Aspen, Russian-Olive (which is in North America), and Euphorbia (it might) all have all five vowels too and are North American. I admit that the Southern Magnolia and Quaking Aspen are two words, and the Russian-Olive has a hyphen, but I see no reason for not including the Euphorbia. I hope that you at least mention these in the answers for the logic riddles.
8. One, he may have many Birthdays, but only one birth day!
9. Mother, or Mom, or whatever you call your maternal relative.
10. The answer is actually feathers. We need proof though! AND SO
a pound of feathers is more than one pound of gold because the "pound" unit is different. The most commonly used system of weights in the US and Great Britain is the avoirdupois system, where 1 pound = 16 ounces. This is used for most solid objects, except for precious metals and gems; gold is weighed by a special system, called the troy system, where one troy pound = 12 troy ounces. Where one avoirdupois ounce is 28.35 grams, one troy ounce is about 31.10 grams. To convert from avoirdupois pounds to troy pounds, multiply the first by 1.2152 to get its equivalent in troy measurement. Therefore, one "pound" of feathers in troy weight is actually 1.2152 pounds (one avoirdupois pound), compared to one troy pound of gold. And the feathers win.
