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?
Grandmother....Is that you?
A woman goes to the local psychic in hopes of contacting her dearly departed grandmother. The psychic's eyelids begin fluttering, her voice begins warbling, her hands float up above the table, and she begins moaning. Eventually, a coherent voice emanates, saying, "Granddaughter? Are you there?"
The customer, wide-eyed and on the edge of her seat, responds, "Grandmother? Is that you?"
"Yes granddaughter, it's me."
"It's really, really you, grandmother?", the woman repeats.
"Yes, it's really me, granddaughter."
The woman looks puzzled, "You're sure it's you, grandmother?"
"Yes, granddaughter, I'm sure it's me."
The woman pauses a moment, "Grandmother, I have just one question for you."
"Anything, my child."
"Grandmother, when did you learn to speak English?"
