118 The following from rjsiekman; Think of it as the number of times the 3 will be written in the hundreds, tens, and ones column. This analysis assumes whole numbers; otherwise you can write a 3 an infinite number of times. In the hundreds, 301.....399 is 99 (because it is stated the numbers between 300 & 400; 300 is not included). In the tens, 3 will be written for 330....339 which adds another 10. In the ones, 3 will be written for 303, 313....393 which adds another 10. So, in total, the 3 will be written 119 times.
