In each square, top left number shows the number of line workmen and bottom right corner shows the number of staff. These two constitute the employees.

We know
Total = n(A) + n(B) - Both + None
None = Total - n(A) - n(B) + Both

Calculate "none" for each case

None(5+ yrs Line) = 200 - 50 - 40 + 30 = 140
None(5+ yrs Staff) = 160 - 40 - 50 + 20 = 90

Employees not taking either workshop/Total number of employees = (140 + 90)/(200 + 160) = 230/360 = About 64%

Total = Stress workshop + first aid workshop - taking both workshops +
neither workshop = Total - Stress workshop - first aid workshop + taking both workshops
= 360 - 90 - 90 + 50
= 230

Percentage = (230*100/360)=64%
