Wow, here it is February already and the best part is Spring is right around the corner. It has been a pretty hard winter across the US, at least here in south central Kansas, and I'm sure everyone is looking forward to warmer days and getting out and working in the yard. Of course with February comes Valentine's Day, a special day for people to show their affection and love for one another. Reds, pinks, and whites seem to be the prominent color and hearts, cupids, boxes of chocolates, and stuffed animals the prominent gifts. So Happy Valentine's Day!

It has aready started to snow when Miss Scarlet, Mr. Green, Mrs. Peacock, Mrs. White, and Prof. Plum headed to the store to pick up one item they had forgotten to get the day before while stocking up for the blizzard forecasted. They found themselves standing in one lane, 1st through 5th, and chit chatted while their orders were being rung up. In addition to the one item each forgot - bread, cereal, eggs, milk, and peanut butter - each also bought a snack item (bar-b-que flavored potato chips, cheese flavored popcorn, corn chips, mixed nuts, and pretzels) to eat that night while relaxing in his or her warm home while the storm swirled around. From the clues determine the order of each person in line, the item of food each had forgotten to get the day before, and the snack each purchased.
1. Mrs. White was in line somewhere in front of the person who was buying cereal and immediately behind the person who purchased the cheese flavored popcorn.
2. The individual who purchased the pretzels did not stand immediately next to the person who purchased the can of mixed nuts, and neither of these two people are the individual who had forgotten to buy eggs the day before.
3. The person who purchased the bread stood immediately behind the one who bought the bar-b-que flavored potato chips to snack on, and at most two people separated the person who purchased the bread from Mrs. Peacock, who was further back in the line.
4. Mr. Green was neither the person who forgot to buy peanut butter nor the person who forgot to buy eggs.
5. Prof. Plum was neither the first nor the last person in line.
6. It wasn’t Mrs. Peacock who had forgotten to buy cereal on her prior visit.
7. Miss Scarlet (who didn’t but a can of mixed nuts) stood in line somewhere in front of the person who bought the bag of corn chips and somewhere behind the person who had forgotten eggs the day before while shopping.

Note: I’m always getting email from visitors either with a challenge to solve a problem similiar to some of the following, or they are having problems solving it and would like my help. This section is one where a person can come and try and find the answer. A lot of these I had collected into a folder of logic problems of several types or found on the Internet, and I really don’t recall the sources where I got them it was so long ago. Many of these I’ve found in several different sources without copywrite facts, so if these are the copywrited material of any particulalr person and he or she wants them removed, please contact me and I’ll be glad to do so immediately.
A Little Legal Problem
1. A and B were walking down the street when they met C. An agruement arises between the three, with C assulting B, and in turn, A then kills C. A, and B go to court and, of course, and A is found guilty of murder. However, even though there was no question of the guilt of A, he was able to walk out of the court a free man. How can you explain this?
2. Whose Picture Am I Looking At?
Despite the fact that this particular puzzle and its variation has been around for years, many people still get them wrong. Here are the problems:
A. A man was looking at a portrait. Someone asks him, “Whose picture are you looking at?: He replied: “Brothers and sisters have I none, but this man’s father is my father’s son. (“This man’s father” means, of course, the father of the man in the picture.) So, whose picture was the man looking at?
B. A variation on this problem would be if the man had said “Brothers and sisters have I none, but this man’s son is my father’s son.” Now, whose picture is the man looking at.
3. The Bookworm
A little bookworm eats his way from page 1 of Volume I to the last page of Volume II of a two-volume work. The books are standing on a bookshelf in the usual manner with the bindings facing out. If the pages of each volume are 2" thick and the covers 1/4" thick, how many inches did the bookworm chew.
4. Spreading Amoeba
If you could count the number of amoeba in a certain container, you would find that there were twice as many there as on the previous day. And if you counted again on the following day, you would find twice as many as you found today. Assuming this rate of growth is normal for amoeba, and that a certain container would be full of amoeba in 60 days, on which day would the container be half full?
5. Dividing Cells
Similiar to the amoebra problem above, in this one involves cultivation of cells. Each cell splits into two cells after one minute. One minute later the two cells split to make four, then the four cells split to make eight, and so on. Every minute the number of cells doubles. Assume that it takes an hour for one cell to grown until the bottle is full. If one starts with two cells, how long will it take to fill the same bottle?
6. The Sock Man I
This one has been around for ages, and yet some people still have to think about it. There is a man who wears only two color of socks, either black or red. He keeps them all in a drawer in a state of complete disorder. In total there are 10 black socks and 10 red socks. Assuming that the electricity fails while the man is dressing, so he is unable to see the colors of the socks in the drawer, how many socks must he remove from the drawer in order to be he gets a matching pair?
7. The Sock Man II
Suppose there are some black socks and the same number of red socks in a drawer. Suppose it turns out that the minimum number of socks a man must pick in order to be sure of getting at least one pair of the same color is the same as the minimum number he must pick in order to be sure of getting at least two socks of different colors. How many socks are in the drawer?
