If all of the employees of Company K who worked there last January are still there, how many employees does Company K have now?

1) Last January the ratio of the number of male employees to the number of female employees was 2 to 3.
2) Since last January, Company K has employed 400 new male employees and no new female employees, raising the ratio of the number of male employees to the number of female employees to 3 to 4.

(1) \(\frac{m}{f}=\frac{2}{3}\), only the ratio is given, hence clearly insufficient to determine the numerical value of employee.

(2) \(\frac{m+400}{f}=\frac{3}{4}\). The same as in (1). Not sufficient.

(1)+(2) Two different equations, two variables, hence we can calculate \(m\) and \(f\). \(m+f+400\) would be the # of employees now.

Answer: C.

Two different equations, two variables

Yeah, that's the key!
