ATQ, Let total amount of work = 630 units (LCM of 90 and 70) Efficiency of ‘Preeti’ = 630/70 = 9 units per day Efficiency of ‘Bhanumati’ = 630/90 = 7 units per day Amount of work completed by ‘Preeti’ and ‘Bhanumati’ together in 23 days = 16 × 23 = 368 units Remaining work = 630 – 368 = 262 units Efficiency of ‘Bhanumati’ and ‘Chirag’ together = 262/(131/6) = 12 units per days So, efficiency of ‘Chirag’ = 12 – 7 = 5 units per day Hence required time = 630/5 = 126 days
