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

Late one Sunday afternoon, a blonde from a Pennsylvania small town was taking a long walk through a nearby meadow, when she was surprised to see a parachutist trapped in the high branches of a tree.
"Help!" he cried when he spotted her down below.
"What are you doing up there?" she called back.
"I was skydiving," he answered, "and my parachute didn't open!"
The blonde rolled her eyes: "Well, of course it didn't. If you'd just asked one of the locals, anybody could've told you that nothing around here opens on a Sunday!"
