I am a 3 digit number.It's ??? (LOL)
The digit in the hundreds place is 4 times the digit in the ones place.So it can only be either 4?1 or 8?2
The sum of all the digits is 17.That rules out 4?1, so it has to be 8?2. Then the digit where the question mark is
has to be 7, so that the digits will have sum 17.
The digit in the tens place is an odd number.That's true but we didn't need that information to
get it.
what number am 1?872.
