Explanation

Initial total weight: 40 men * 65kg = 2600kg, 50 women * 60kg = 3000kg, total = 5600kg. After resignations: 50% men remain = 20 men (40*65 = 2600kg becomes 20*65 = 1300kg), 60% women remain = 30 women (50*60 = 3000kg becomes 30*60 = 1800kg). New total = 1300 + 1800 = 3100kg. New average = 3100/50 = 62kg. The average changes because the remaining group composition differs from the original.
