**Reiny**, Sunday, August 4, 2013 at 10:02pmQuestion:

Can digits be repeated,

e.g. is 332 allowed as a 3 digit number?

both groups must end with a "2"

I will assume digits may repeat

number of 3 digit even numbers = 4x4x1 = 16

number of 4 digit even numbers = 4x4x4x1 = 64

total = 80

mmhhh?

suppose we can't repeat

3digit evens = 3x2x1

= 6

4digit evens = 3x2x1x1 = 6

that would be only 12 total

something is not right with your choices.

Am I reading the question correctly?
