Two of my digits are even, my last digit is odd, the sum of my digits is 11. I'm between 256 and 299, and I'm not 281. What am I?

You are 263.

Two of the digits are even. 2 and 6.

Last digit is odd. 3 is odd.

Sum of digits is 11. 2 + 6 + 3 = 11.

And 263 is between 256 and 299.

Ok so

2 digits even, last is odd

sum is 11

between 256 and 299

not 281

ok so we take 3 facts

sum is 11

between 256 and 299

2 are even

between 256 and 299, the first number is always 2

therefor

2+x+y=11

x+y=9

the other 2 numbers add up to 9

write all 2 ditgit numbers between 56 and 99 that add up to 9

63,72,81,90

not 281 so get rid of 81

and last diti is odd and first 2 are even so get rid of 72 and 90

therfor is it 63

263
