Answer» Answer: Step-by-step explanation: If A can do a PIECE of work in N days, then A's 1 day's work = 1/n (A+B+C)′s 1day's work=1/6 + 1/12 + 1/24 = 7/24 Formula: If A's 1 day's work = 1/n , then A can finish the work in n days So, all the three together will complete the JOB in 24/7 days=3 3/7 days |
