Answers
Answer:
C) 1012 hrs
Description for Correct answer:
Part of work done by both A and B alternatively in 2 hrs.
= 18+116=316
Therefore, 316 part of work is done in 2 hrs.
Therefore, Complete part of work is done in
23×16=10.66hrs.
i.e. 10 hrs. + some minutes
Part of work completed in 10 hrs.
102×316=1516
Therefore, Remaining part of work is done by A.
i.e. 1−1516=116 part of work is to be done by A.
Therefore, Time required by A to complete 116th part of work
= 12hr.
Hence total time taken by A and B alternatively to complete the work is
(10hrs+12hr)=1012hrs.
