Using the digits 1, 2, 3, 4, 5, how many even three-digit numbers less than 500 can be formed if each digit can be used more than once?

Both answers, in the link above, give a total of 40. Can somebody tell me what is wrong with this list?

 

112   114   122   124   132   134   142   144   152   154   212   214   222   224   232   234   242   244   252   254   312   314   322   324   332   334   342   344   352   354   412   414   422   424   432   434   442   444   452   454    Total =  40

The numbers have to be < 500

 

Thus....your last 10  aren't included
