Someone please help to solve DS question:
Each employee is either a director or a manager. What % of the employees are directors?
a. The average salary of managers is $5000 less than the average of all employees
b. The average salary of directors is $15000 greater than the average of all employees
Thank you in advance.
Best regards.

St1: Does not say anything about avg salary of Directors INSUFFICIENT

St2: Does not say anything about avg salary of Managers INSUFFICIENT

Together: Sufficient
we know ratio of managers to directors is 3:1 as avg salary of managers is 5 units away from avg while salary of directors is 15 units away from average.

Ans C
