    First aicraft is 216 seats

    Second aircraft is 104 seats

    Third aircraft is 72 seats

    Step-by-step explanation:

    Let 2nd air. = x

    Let 1st air. = x+112

    Let 3rd air. = x-32

    Total seats = 392

    1st + 2nd + 3rd = 392

    (*+112) + (x) + (x-32) = 392

    x + 112 + x + x - 32 = 392

    3x + 80 = 392

    3x = 312

    x = 312/3

    = 104

    1st aircraft = x+112

    = 104 + 112

    = 216 seats

    2nd aircraft = 104 seats

    3rd aircraft = x-32

    = 104 - 32

    = 72 seats
