Question
Find the difference between the total staffs at βYβ
and βZβ.Solution
Let the number of female staffs at βZβ be βxβ Therefore, number of male staffs at βXβ = (x + 480) Number of male staffs at βZβ = 1.25(x + 480) According to the question, => (x + 480) + 600 + 1.25(x + 480) = 2220 => 2.25x = 2220 β 1680 => 2.5x = 540 => x = 240Β Β Therefore, number of male staffs at βXβ = (x + 480) = 720 Number of male staffs at βZβ = 1.25(x + 480) = 900 Number of female staffs at βXβ = (1/3) Γ 600 = 200 Number of female staffs at βYβ = 960 β 600 = 360 Required difference = 1140 - 960 = 180
