How many times does the digit 3 appear in the first 40 odd numbers?

Answer 1

Well, honey, the digit 3 appears in every odd number that ends in 3, 13, 23, 33, and so on up to 39. So, in the first 40 odd numbers, the digit 3 appears 4 times. Math doesn't have to be a drag, darling!

Answer 2

The first 40 odd numbers include 40 numbers starting from 1 to 79. To determine how many times the digit 3 appears in these numbers, we can first look at the units digit. Every 10 numbers, the units digit will cycle through 1, 3, 5, 7, and 9. Therefore, the digit 3 will appear 4 times as the units digit in the first 40 odd numbers.
