  • algebra -

    first part --- x
    2nd part --- y
    3rd part ---- 50000-x-y

    interest on 1st = .08x
    interest on 2nd = .06y
    3rd interest = .09(50000-x-y)

    but .08x = 2(.06)y
    8x = 12y
    y = 8x/12 = 4x/3

    .08x + .06y + .09(50000-x-y) = 3960
    sub in y = 4x/3 and solve

    I am sure you can take it from here
