Answer:
There are 50 full-time and 25 part-time employees in the company.
Step-by-step explanation:
Total number of employee in the company = 75
Employee's records to be audited = 50
Number of audited record = 75 - 50
                      = 25
Records of employees to be audited = 50
Since half of the full-time employee's records has been audited after 3-days, then the number of full-time employee = number of audited record x 2 = 25 x 2
                         = 50
The number of part-time employee's in the company = 75 - 50
                         = 25
There are 50 full-time and 25 part-time employees in the company.
