Question
40 tailors can stitch a batch of dresses in 30 days. If
20 tailors started the job and after 15 days ‘u’ more tailors joined them such that the remaining work got completed in 15 days, then find the value of ‘u’.Solution
Total work = 40 × 30 = 1200 units Work completed by 20 tailors in 15 days = 20 × 15 = 300 units Remaining work = 1200 – 300 = 900 units Let the number of tailors added be ‘u’. Therefore, (20 + u) × 15 = 900 300 + 15u = 900 15u = 600 u = 40 Number of tailors added = 40
