Let the initial total number of employees be 100N number of employees in research = 60% of 100N = 60N number of employees in marketing = 20% of 100N = 20N number of employees in development = 100% - (60% + 20%) = 20% of 100N = 20N total number of employees in company after restructuring = 120% of 60N + 90% of 20N + 20N 770 = 72N+18N+20N 770 = 110N N = 7 the initial total number of employees = 100N = 700
