If you are explaining it correctly it should be 64. That is the first row of numbers 1 - 10 contain one 4. 11 - 20 contain another 4 this continues untill you get to the 40's which contain 9 fours, one in each number. However, you didn't specify if 44 is counted twice but I'm assuming it is once since you are saying that a number contain a digit 4 not digits. Therefore you keep counting and 64 is the last number totaling 15 numbers containing the digit 4.
