Answer 1

According to the question:

From 1 to 100 there are 10 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

∴ 3 is written 20 times

Hence, "Option 3" is the correct answer.
