There are four three-digit numbers that share this property: the number itself, its double and its triple contain each digit from 1 to 9 exactly once. For example, 192 is one of them because 192, 384, 576 contain 1 to 9 each once. 273 is another one of them because 273, 546, 819 contain 1 to 9 each once. Can you find the other two numbers and calculate the product of these two numbers?Correct answers: 23

A man asked his wife...
A man asked his wife, "What would you most like for your birthday?"
She said, "I'd love to be ten again."
On the morning of her birthday, he got her up bright and early and they went to a theme park. He put her on every ride in the park - the Death Slide, The Screaming Loop, the Wall of Fear. She had a go on every ride there was. She staggered out of the theme park five hours later, her head reeling and her stomach turning. Then off to a movie theater, popcorn, cola and sweets.
At last she staggered home with her husband and collapsed into bed.
Her husband leaned over and asked, "Well, dear, what was it like being ten again?"
One eye opened and she groaned, "Actually, honey, I meant dress size!"
