* A Tricky Walk

    "You'll never believe what I saw at 5:00 this morning!" Carmen said to her friend Pat. "I was riding my bike to Townsville to deliver papers. I was all alone, when suddenly I saw this strange parade coming toward me.
     "It was the circus coming to town. First there were three elephants, with two men riding on each of them. Then there were four big white horses, and they each had two women riders. Last of all, there were two open trunks. One had three clowns juggling balls. The other had three more clowns doing handstands and cartwheels. You should have seen them!
    "Anyway, here's a question for you. How many people in all were on their way to Townsville at 5:00 this morning?"
    "Wait a minute!" said Pat. I can't remember everything you told me!"
Can you? How Many People were there?

* How Many Cookies?

    Karen and five friends were sitting in the kitchen when her Aunt Margo walked in. She pointed to a large plate on the counter.
     "Well!" she said. "I left an odd number of cookies on that plate. Now it's turned into a different odd number. Isn't that odd?"
     There were three cookies left.
     "It's my birthday, so we ate some," said Karen. "Is that odd?"
     "No," said Aunt Margo. "But the number was important. It's my birthday tomorrow. The number of cookies showed your age today and my age tomorrow."
     "How could it do that?" said Karen. "You're several times older than I am."
     "You'll see," said Aunt Margo. "Did anyone notice how many cookies there where?"
     The children all shook their heads no.
     "Then let's work it out," said Aunt Margo. "How many cookies did you have each?"
     Karen had 3. Maria, Lester, and Nikki each had 4. Kevin had 5. But Liza wasn't sure if she had 3 or 4.
     "Well never work it out," Karen sighed.
     "Sure you will," said Aunt Margo. "Just do a bit of odding - I mean adding - and you'll have the answer in a flash!"
Can you help them?
