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

One morning a blind bunny was hopping down the bunny trail and tripped over a large snake and fell, kerplop right on his twitchy little nose.
'Oh please excuse me,' said the bunny. 'I didn't mean to trip over you, but I'm blind and can't see.'
'That's perfectly all right,' replied the snake. 'To be sure, it was my fault. I didn't mean to trip you, but I'm blind too, and I didn't see you coming. By the way what kind of animal are you?'
'Well, I really don't know,' said the bunny. 'I'm blind, and I've never seen myself. Maybe you could examine me and find out.'
So the snake felt the bunny all over, and he said, 'Well, you're soft, and cuddly, and you have long silky ears, and a little fluffy tail and a dear twitch little nose. You must be a bunny rabbit.'
The bunny said, 'I can't thank you enough. But, by the way, what kind of animal are you?'
The snake replied that he didn't know either, and the bunny agreed to examine him, and when the bunny was finished the snake asked, 'Well, what kind of animal am I?'
The bunny had felt the snake all over, and he replied, 'You're cold, you're slippery, and you haven't any balls............You must be a politician!'
'Oh please excuse me,' said the bunny. 'I didn't mean to trip over you, but I'm blind and can't see.'
'That's perfectly all right,' replied the snake. 'To be sure, it was my fault. I didn't mean to trip you, but I'm blind too, and I didn't see you coming. By the way what kind of animal are you?'
