Explanation

When 'OR' is used in work-time problems, it means the work rates are equal. Here, 2 Men and 5 Women both complete the work in 16 days, so they have equal rates. Therefore, 2 Men + 5 Women working together equals 4 Men working. If 2 Men take 16 days, then 4 Men (double the workforce) take half the time: 16/2 = 8 days.
