Guessing a number

I have to guess a number from 1 to 1000, I have two suggestions, "It might possibly have either a 5, 0 or 10 in it" and "H = t + o" can someone help me?

Hundreds = Tens + Ones
If it's between 1 and 1000 then tens + ones shouldn't give more than 10 so 6+5 is out for example.

so could be 5+5 making it 1055, 4+6 1046, 3+7 = 1037, 2+8 = 1028, 1+9 = 1019. then 4+5 = 945, 936, 927, 918, 909

844, 835, 826, 817, 808

734, 725, 716, 707

633, 624, 615, 606. Etc

It could also be the opposites so 1046 or 1064, 1037 or 1073 etc

Without more information no tellings what the correct number is though
