      Solution

      Total number of male employees who are married = 120 Total number of male employees (married + unmarried) = (120/30) × 100 = 400 Number of male employees who are unmarried = 400 − 120 = 280 Total number of female employees = 840 − 400 = 440 Total number of female employees who are unmarried = 280 − 180 = 100 Number of female employees who are married = 440 − 100 = 340 Required difference = (120 + 340) – (280 + 100) = 460 – 380 = 80
