Question

14. A, B and C can do a piece of work in 6, 8, and 12 hours respectively. They started the work together and after 1 hour B left the work. In how much time will the remaining work be completed by A and C? ​

Answer 1

Step-by-step explanation:

Work done by B & C in 2 days = 2×{81+121}

= 125th part of thw work

Remaining work = (1−125)th=127th park

A and B's one day work = (61+81)th=(247)th part

So 247th part of work is completed in 1 day

∴ 127th part of work will be completed in

= 2471×127=2 days
