**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.

**Problem 2 – Examples of Odd Numbers**

Which of the following is an odd number?

131, 140, 156, 162

**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, 131 is not divisible by 2

Therefore, 131 is an odd number.

**Problem 3 – Examples of Odd Numbers**

Which of the following is an odd number?

490, 502, 878, 473

**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, 473 is not divisible by 2

Therefore, 473 is an odd number.

**Problem 4 – Examples of Odd Numbers**

Which of the following is an odd number?

1547, 1556, 1572, 1578

**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, 1547 is not divisible by 2

Therefore, 1547 is an odd number.

**Problem 5 – Examples of Odd Numbers**

Which of the following is an odd number?

1772, 1765, 1770, 1762

**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, 1765 is not divisible by 2

Therefore, 1765 is an odd number.

**Problem 6 – Examples of Odd Numbers**

Which of the following is an odd number?

3894, 3806, 4356, 3877

**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, 3877 is not divisible by 2

Therefore, 3877 is an odd number.
