You don't mean "3 possible digit combinations"; you mean "3-digit possible combinations"and you also forgot to specify that the first digit can't be zero.(We wouldn't have known that, but two of your buddies asked the same questionabout 7 hours before you did.)The question is describing all of the counting numbers from 100 to 999.That's all of the counting numbers up to 999, except for the first 99.So there are 900 of them.
The smallest 5-digit integer perfect square is 10,000 = (100)2The largest 5-digit integer perfect square is 99,856 = (316)2So we want to know how many numbers that is, from 100 to 316 inclusive.It's 316 minus the first 99 = 217 of them.
Answer is 19. Explanation: we look at the entire range 99 to 131, in smaller groups. 99 has no digit 1. 100 to 109 have nine numbers with only one "1". 110 to 119 have no numbers with only one "1". 120 to 129 have nine numbers with only one "1". 130 has one number with only one "1". 131 does not have only one "1". Total: 9 + 9 + 1 = 19
