Since the ratio of upper-management to middle management personnel is 4:3, U:M = 4x:3x
Since 75% of the upper management has experience on the production line, $$\frac{3}{4}*4x = 3x$$

Therefore, the greatest proportion of total of upper and middle management personal is $$\frac{3x+3x}{3x+4x} = \frac{6x}{7x} = \frac{6}{7}$$(Option C)

Can u explain how is it 3x+3x?
