Q. In an annual seminar, three companies A, B, and C are represented by male and female employees. The average number of female employees representing companies A and B is 420. The total number of male employees representing A and B together is 1620. The number of female employees is $\frac{5}{9}$ of the number of male employees in A and B combined. The total female employees representing company C are 25% more than the total female employees representing company A. The total male employees representing company C are 33% more than the total female employees representing company B.

If 25% of the total female employees and 20% of the total male employees representing companies B and C together have an MBA degree, what is the total number of employees who do not have an MBA degree?
