Of the 200 employees at Company A, 70 work part-time and the rest work full-time. If 140 of the employees like their jobs and 10 of the part-time employees don’t like their jobs, how many full-time employees like their jobs?

A. 50
B. 60
C. 80
D. 130
E. 140

Answer: C

Solution:

We see that there are 70 part-time employees, and thus there are 200 - 70 = 130 full-time employees. Since 10 of the part-time employees don’t like their jobs, then 60 part-time employees do like their jobs. We know that a total of 140 employees do like their jobs, so we subtract the 60 part-time employees who like their jobs to determine that 140 - 60 = 80 full-time employees like their jobs.
