Answer:

The value of 30 is 1.

Explanation:

To understand why the value of 30 is 1, we need to look at the options given and analyze them one by one.

Option (a): 1
Option (b): 3
Option (c): 9
Option (d): None of these

Let's consider each option and see if it matches the value of 30.

Option (a): 1
If we divide 30 by 30, we get 1. So, option (a) is correct.

Option (b): 3
If we divide 30 by 10, we get 3. So, option (b) is not correct.

Option (c): 9
If we divide 30 by 3, we get 10. So, option (c) is not correct.

Option (d): None of these
Since option (a) is correct, option (d) is not correct.

Therefore, the correct answer is option (a), which states that the value of 30 is 1.

In this case, the value of 30 is obtained by dividing 30 by 30, which equals 1. It is important to note that the value of a number is determined by the operation or calculation performed on it. In this case, the division operation helps us determine the value of 30.

It is crucial to read the question carefully and analyze the options provided before arriving at the correct answer.
