    1st integer: x
    2nd : y
    3rd : z

    Sum of three integers:
    x + y + z = 247 (1)

    Sum of first 2 exceeds the 3rd by 95. In another word, sum of first two is larger than the 3rd by 95:

    (x+y) - z = 95 (2)

    Third is less than first 85:

    x = z + 85 (3)

    Take (1) minus (2)
    x + y + z = 247
    -
    x + y - z = 95
    ----------------------
    2z = 247 - 95 =??

    Then divided by 2 to get z

    Since you get z, plug into (3) to get x.
    When you get x and z, plug x and z either in (1) or (2) to get y.
