Question 5821
it doesn't say how to solve this, so i will just use common sense...


Possible numbers are:
255
265
275
285
295
305
315
325
335
345


The sum of their digits are the same...ignore the 5 since all these numbers have a 5...so:

25 --> 7
26 --> 8
27 --> 9
28 --> 10
29 --> 11
30 --> 3
31 --> 4
32 --> 5
33 --> 6
34 --> 7


So, straight awy, the answer is there: 255 and 345.
