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

Three little ducks
Three little ducks go into a bar.
"Hello, what's your name?" the bartender asks the first duck.
"Huey," he replies.
"How's your day been, Huey?" the bartender asks.
"Great. Lovely day. Had a ball. Been in and out of puddles all day. What else could a duck want?" smiles Huey.
"That's nice," says the bartender, turning to the second duck. "Hi, and what's your name?"
"Dewey," comes the answer from duck number two.
"So how's your day been, Dewey?" asks the bartender.
"Great. I've had a ball, too. Been in and out of puddles all day, as well. What more could a duck want?"
The barman turns to the third duck and says: "So, you must be Louie?"
"No," she says, batting her eyelashes. "My name is Puddles."
