    108 boys and 81 girls

    Step-by-step explanation:

    If B is the number of boys and G is the number of girls, then:

    B + G = 189

    B - G = 27

    To solve, use substitution or elimination. In this case, I recommend elimination. Add the equations together:

    2B = 216

    B = 108

    Therefore:

    G = 81

    So there are 108 boys and 81 girls.
