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

Since 10 part-time employees don’t like their jobs, 70 - 10 = 60 part-time employees like their jobs. Since 140 employees like their jobs and 60 are part-timers, then 140 - 60 = 80 full-time employees like their jobs.
