Question 241937: The digits 1, 2, 3, 4 and 9 are each used once to form the smallest possible
even five-digit number. The digit in the tens place is
a. 1 b. 2 c. 3 d. 4 e. 9
Answer by Edwin McCravy(20056)   (Show Source):
You can put this solution on YOUR website! 9, choice e.
'
We use the smallest possible digit for the 10000s place, 1.
We use the next smallest possible digit for the 1000s place, 2.
We use the next smallest possible digit for the 100s place, 3.
We would use the next smallest number, 4 for the 10's place, but
since there are only two left, and the number has to be even, we
must save the 4 for the ones digit. So that leaves only 9 for
the tens digit. The 4 has to be the ones digit.
'
So the smallest such even number is 12394, and the digit in the
tens place is 9, choice e.
