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 little girl and boy are fighting about the differences between the sexes, and which one is better. Finally, the boy drops his pants and says, “Here’s something I have that you’ll never have!” The little girl is pretty upset by this, since it is clearly true, and runs home crying. A while later, she comes running back with a smile on her face. She drops her pants and says, “My mommy says that with one of these, I can have as many of those as I want!”
