The whole number whose successor is 53,100 is

1. 53,101

2. 53,099

3. 53,000

4. none of these

The successor of a number is obtained by adding 1 to that number.

Let the whole number be 'x'.

Its successor is given as 53,100.

So, we have the equation:

⇒ x + 1 = 53,100

To find x, subtract 1 from 53,100:

⇒ x = 53,100 - 1

⇒ x = 53,099

The whole number whose successor is 53,100 is 53,099.

Hence, option 2 is the correct option.
