    180

    Step-by-step explanation:

    Let the number of research assistants employed be y

    Given that there are two times as many teaching assistants as research assistants, then

    Number of teaching assistants = 2y

    Since there are 540 employed

    y + 2y = 540

    3y = 540

    y = 540/3

    y = 180

    There are 180 research assistants employed by the university.
