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?
Chalk One Up For The Grandparents!
An elderly man in Miami calls his son in New York and says, "I hate to ruin your day, but I have to tell you that your mother and I are divorcing.
Forty-five years of misery is enough."
"Pop, what are you talking about?" the son screams.
"We can't stand the sight of each other any longer," the old man says.
"We're sick of each other, and I'm sick of talking about this, so you call your sister in Chicago and tell her," and he hangs up.
Frantic, the son calls his sister, who explodes on the phone, "Like heck they're getting divorced," she shouts, "I'll take care of this."
She calls her father immediately and screams at the old man, "You are NOT getting divorced! Don't do a single thing until I get there. I'm calling my brother back, and we'll both be there tomorrow. Until then, don't do a thing, DO YOU HEAR ME?" and hangs up.
The old man hangs up his phone and turns to his wife. "Okay," he says, "They're coming for Passover and paying their own airfares."
