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 job
140 of ALL employees like job 10 of PART-TIME employees don't like job - so remaining 60 of PART-TIME employees like job => 140-60=80 FULL-TIME employees like job
