Let average salary of managers be m , directors be d and overall be x
Statement 1:
m=x-5000
Statement 2:
d=x+15000
Also,
x=(n*d+o*m)/(n+o) where n is no of directors and o no of managers
On solving above there equations you can will get a ratio of n:o as 3:1
So now you can say the percentage of director
