Difficulty—

A certain company currently has how many employees?

(1) If 2 additional employees are hired by the company and all of the present employees remain, there will be at least 20 employees in the company.
(2) If no additional employees are hired by the company and 2 of the present employees resign, there will be 18 employees in the company.

The OA is B.

Let's say that X is the total of employees, then

(1) X + 2 >= 20. Is not sufficient to get the exact number of employees in the company.

(2) X - 2 = 18. Is sufficient to get the exact number of employees in the company.

Hence, B is the correct option.

Is correct my solution? Can anyone help, please? Thanks in advance.

Yes, this is correct. Statement 1 does not give a unique value, while Statement 2 does.
