1 director for 5 managers and 20 workers for 3 managers.... Let us take the number of managers as LCM of 3 and 5 or 15.. so 1 director for 5 managers means 1*3 director for 3*5 managers and 20 workers for 3 managers means 5*20 workers for 3*5 managers.. so the group is 3 director, 15 managers and 100 workers, thus a total of 3+15+100 = 118 Now multiple of 118 between 300 and 400 is 118*3.. Thus managers = 15*3=45
