**Problem 1 – Examples of Odd Numbers**

Which of the following is an odd number?

73, 82, 98, 104

**Solution:**

Numbers which are not divisible by 2 are known as odd numbers.

A number is divisible by 2, if the digit at one’s place of that number is divisible by 2 or digit at ones place is 0, 2, 4, 6, 8.

In other words, if the digit at ones place is 1, 3, 5, 7, 9, it would not be divisible by 2

In present case, 73 is not divisible by 2

Therefore, 73 is an odd number.
