let the lowest salary be x.
Therefore, highest salary is x +30000.
Now salary of each employee is increased by 10%.
Therefore the salaries will remain arranged in the same order as before.
or Lowest salary = 1.1x and Highest = 1.1 * (x+30000)
or Range = highest - lowest = 1.1 * (x+30000) - 1.1x
= 33000, Hence, C
