ATQ, Time taken by ‘B’ to complete the work = 1.5 × 15 = 22.5 days (round up to 23 days) Let the total work = 230 units Efficiency of ‘A’ = 230/15 = 15.33 units/day (round to 15 units/day) Efficiency of ‘B’ = 230/23 = 10 units/day Work completed by ‘A’ and ‘B’ in 8 days = (15 + 10) × 8 = 200 units Therefore, x = (230 – 200)/10 = 3 days
