Answer 2

The sum of 3 odd numbers will always be an odd number. 30 is even, all the numbers provided are odd. If you wrote all the numbers in binary you would see that all the odd numbers have a 1 as the least significant digit so 1+11+101=1001 (1+3+5=9). With even numbers it is opposite 10+100+110=1100 (2+4+6=12).
