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

How was your game, dear?
"How was your game, dear?" asked Jack's wife Tracy.
"Well, I was hitting pretty well, but my eyesight's gotten so bad I couldn't see where the ball went," he answered.
"But you're 75 years old, Jack!" admonished his wife, "Why don't you take my brother Scott along?"
"But he's 85 and doesn't play golf anymore," protested Jack.
"But he's got perfect eyesight. He would watch the ball for you," Tracy pointed out.
The next day Jack teed off with Scott looking on. Jack swung and the ball disappeared down the middle of the fairway. "Do you see it?" asked Jack.
"Yup," Scott answered.
"Well, where is it?" yelled Jack, peering off into the distance.
"I forgot."
