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
