Let the number of employees be 100
Number of people with advanced degree = 20
Number of people with degree = 80
Average salary = \(\frac{20*350000+80*100000}{100}\) = \(\frac{700000+800000}{100}\) = 150000

E is the answer.

let total strength = 100
so
20 * 350000+ 80 * 100000/100
= > 150,000

Let total employees = 10

20% of the employees have advanced degrees = 2, bachelor’s degrees = 8

average salary for the employees with an advanced degree is $350,000, Total salary = $350,000 * 2 = 700000

average salary for employees with a bachelor’s degree is $100,000, Total salary = $100,000 * 8 = 800000

average salary, in dollars, for all the employees at Alioth Industries = \(\frac{{700000 + 800000}}{10}\) = 150,000
