Explanation

28 men + 52 women complete work in 22.5 days. Assuming constant work rates, 35 men + 65 women is 1.25 times the original workforce (since 35/28 = 65/52 = 1.25). Time = 22.5/1.25 = 18 days. The ratio of men to women remains constant (28:52 = 35:65 = 7:13), making this calculation valid.
