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

Travel With A Horse
An out-of-towner drove his car into a ditch in a desolated area. Luckily, a local farmer came to help with his big strong horse named Buddy.
He hitched Buddy up to the car and yelled, "Pull, Nellie, pull!" Buddy didn't move.
Then the farmer hollered, "Pull, Buster, pull!" Buddy didn't respond.
Once more the farmer commanded, "Pull, Coco, pull!" Nothing.
Then the farmer nonchalantly said, "Pull, Buddy, pull!" And the horse easily dragged the car out of the ditch.
The motorist was most appreciative and very curious. He asked the farmer why he called his horse by the wrong name three times.
"Well... Buddy is blind and if he thought he was the only one pulling, he wouldn't even try!"
