If you write down all the numbers from 1 to 100, then how many times do you write 3 ?
11
18
20
21
Answer: Option
Explanation:

Clearly, from 1 to 100, there are ten numbers with 3 as the unit's digit- 3, 13, 23, 33, 43, 53, 63, 73, 83, 93; and ten numbers with 3 as the ten's digit - 30, 31, 32, 33, 34, 35, 36, 37, 38, 39.

So, required number = 10 + 10 = 20.

According to me, the correct answer is 19 and not 20. You cannot account for 33 twice.

33 is counted double.

Treat 3 as ones digit different to 3 use as a tens digit.

Hope you will understand.
