Question
12 children and 18 men complete an artwork in 9 days.
Each child takes twice as long as a man to finish the artwork. How many days will it take for 18 men to complete the same artwork?Solution
From the question, Capacity of 2 children = Capacity of 1 man. Let 18 men take x days to complete the artwork. M ₁D₁ = M2 D2 (12 children + 18 men) × 9 = 18 × x (6 men + 18 men) × 9 = 18 × x 24x9 =18x 24x9 = 18x x= 12 days
