Answer:
250
Step-by-step explanation:
I guess you could say use casework to solve this problem. You can go through numbers 1 - 99 to find the digit 2 appears 20 times, 10 times in the units digits, 10 times in the tens digit. Let's proceed to 100-199, where you see, again, 2 appears 20 times. 20+20=40 times already. We need 66 more numbers. Well, since now we're in the 200s, each number has a 2 located in it. 199+66=250
