    E None of these Correct Answer Incorrect Answer

    Solution

    Let the number of female staffs at ‘Z’ be ‘x’ Therefore, number of male staffs at ‘X’ = (x + 480) Number of male staffs at ‘Z’ = 1.25(x + 480) According to the question, => (x + 480) + 600 + 1.25(x + 480) = 2220 => 2.25x = 2220 – 1680 => 2.5x = 540 => x = 240   Therefore, number of male staffs at ‘X’ = (x + 480) = 720 Number of male staffs at ‘Z’ = 1.25(x + 480) = 900 Number of female staffs at ‘X’ = (1/3) × 600 = 200 Number of female staffs at ‘Y’ = 960 – 600 = 360 Average number female staffs at hotels X and Z = (200 + 240)/2 = 220
