If each child gets 8 cards, there is one card left over. But if each child instead gets 5 cards, then there is a stack of 19 cards left over. How many children are playing cards. The hidden words are the six types of chess pieces: Queen (enriQUE ENcountered), bishop(rubBISH OPenly), rook(cROOKed), pawn(shoP AWNings), knight(weeKNIGHTS), and king(maKING) 2012/02/06 00:00:00 Below are two common words encoded using two very simple(but different) encoding schemes. Figure out the words, and then explain the event suggested by this encoding. ROQHMF GBMM Short answer: 6 children. Longer answer: The total number of cards is 8C+1 (8 cards each, 1 left over) and 5C+19 (5 cards each, 19 left over). So we can then work this out algebraicly. 2012/02/13 00:00:00 The winning lottery ticket is a four-digit number containing no zeros and no repeated digits. The sum of the second and fourth digits is the first digit; the sum of the first and fourth digit is the third digit, the first and fourth digits are odd numbers; and the difference between the third and second digits is greater than 2. What is the winning four-digit number? The words are SPRING and FALL. The process to getting to these words is shifting the letters one place forward for spring, and one place back for fall. 2012/02/20 00:00:00 Four people wish to cross a bridge in the dark of night, but the bridge will only support a maximum of 2 people at a time. Furthermore, it's dark and they only have one flashlight, so they have to make a trip back with the one flashlight. Walking alone, the four people would take 1,2,5, and 10 minutes, respectively, to cross the bridge. If two people travel together, they travel at the speed of the slower person. How can you get all 4 people and the flashlight across the bridge in 19 minutes total? Short Answer: 5283. Long answer. first digit(1)- is an odd number, and a+d can't be over 9. Since digit 2 (2) + digit 4(4) will add up to the first digit, and since 1+4 = the third digit, we can reduce all the possibilities down to 7681, 5283, 5461 and 3241. Since the difference of the third and second digits must be greater than 2, we are left with only 5283. 2012/02/27 00:00:00 The initials od a famous, honored American form a sequence of four adjacent letters in reverse alphabetical order. Who is this person. (Hint: his birthday is January 15th) This can take as little as 17 minutes if you plan correctly. Send over 1 and 2 -- Time elapsed: 2 minutes 2 returns with the flashlight -- time elapsed 4 minutes Send over 5 and 10 with the flashlight -- time elapsed 14 miuntes 1 returns with the flashlight -- time elapsed 15 minutes send over 1 and 2 with the flashlight -- time elapsed 17 minutes 2012/03/05 00:00:00 Think of a five-digit number with no repeated digits. The third digit is double the first digit. The second digit is two less than the third digit. The fourth digit is two more than the third digit. The last digit is the sum of the first two. What is the five digit number. Martin Luther King Jr. 2012/03/12 00:00:00 An oxymoron is a word or phrase that contains contradictory elements, like "Open secret" or "same difference". Complete the following oxymorons with the missing words. Original C_____________ Pretty U_____________ Guest H_____________ Random O_____________ Never A______________ Baby G_____________ Short Answer: 34687 Long Answer: if the first digit is A, then a set of algebraic expressions can be used to find all 5 digits, where all of them are based on A, those expressions are as follows. (1.) A, (2.) 2A-2, (3.)2A, (4.)2A+2, (5.) 3A-2. Once you solve for those you realize that A can only equal 3, and the rest solves itself accordingly. 2012/03/19 00:00:00 Some years have the same calendar, since there are only so many different calendars. For example, the calendar for the year 2010 is the same as the calendar for the year 1971. How many different calendars are possible? In order: Original Copy Pretty Ugly Guest Host Random Order Never Again Baby Grand 2012/03/26 00:00:00 A Palindrome is a number (or word) that reads the same forwards as it does backwards. For example the numbers 55 and 282 are palindromes. If the odometer of a car reads 42935, what are the fewest number of miles you could drive to have the odometer show a palindrome? Short answer: 14 Long Answer: Calendars start with January 1st, that means that depending on the day of the week January 1st falls on that the week can be different. Then you need to double that number to account for leap years. 2012/04/02 00:00:00 What is the smaller angle measured in degrees, between the hour and minute hands of the clock at 8:43 am? Short Answer: 99. Long answer: after 99 miles had been driven you would be at 43034 which is the same both backwards and forwards. 2012/04/09 00:00:00 An 8x8x8 cube is painted green on the outside and then cut into 512 1x1x1 cubes. How many of these cubes are painted green on at least 2 sides? Short answer: 3.5 degrees Long answer: The easiest way to figure this is that the hour hand moves 360 degrees every 12 hours, so it moves 1/2 of a degree every minute. The minute hand moves 360 degrees an hour, and thus moves 6 degrees every minute. Thus we find the number of minutes since the hour hand was at 0 degrees, and then do the same for minutes. The minute hand is 12 degrees back from the 9, the hour hand is 8.5 degrees back from the 9, thus we subtract the two and find an angle of 3.5 degrees. 2012/04/16 00:00:00 Spell five 7-letter words with the help of these scrambles.

When you buy 18 chocolate truffles at regular price, you can buy 3 more at the cost of only 6 cents each! If 21 chocolate truffles cost $8.82 while on sale, what is the regular price of once chocolate? 1. Phantom 2. Perform (or preform) 3. Problem 4. Premium 5. Pilgrim 2012/04/30 00:00:00 Final Week-- No riddle, only last week's solution! Short answer: 0.48 Long answer: We can find the cost of a single chocolate by taking 8.82 and subtracting the chocolates that were on sale, their total would be 0.18 (0.06*3). That will leave us with the total of $8.64, which we would then divide by 18, to represent the cost of 18 units. The final cost for a single unit is 0.48
