I am greater than 10 but less than 20. The sum of my digits is 5. What number am I? greater than 10 but less than 20. The sum of my digits is 5. What number am I.

Ok your less then 20 that brings us to every choice below 20 but greater then 10 so it can only be numbers within a range of 20 and 10 the digit is 5 and 15 being the only number within that range with a number 5 within the 10ths place that gives our final estimate answer 15

1+4=15

because 1 and 4 are less than 20 and the sum (15) is greater than 10
