    Boys to girls
    11 : 9

    11x – 124 = 9x
    -124 = -2x
    x = 62

    Check:
    11*62 = 682
    9*62 = 558
    682 – 558 = 124 🙂

    682 + 558 = 1240 students

    Answer:

    number of students=1240

    Step-by-step explanation:

    BOYS TO GIRLS-11;9

    boys=11\20

    girls=9\20

    11\20-9\20=2\20

    2\20=124

    20\20=20\20×124÷2\20=20\20×124×20\2=1240
