Question

find a number that: it is a 3 digit number larger than 399 and smaller than 500 both digits in the tens place and ones place are odd and their sum is equal to 5 the digit in the ones place is larger than the digit in the tens

Answer 1

if the digits are a,b,c we see that
a=4

Then we are doomed. If b and c are both odd, they cannot sum to 5, which is also odd.

And how about a little punctuation? That run-on sentence is very annoying.

Answer 2

The number are 432,441
