Answer 1

Answer:

12 Days

Step-by-step explanation:

A+B alternatively can do a work in 11 days and B+A alternatively can do a work in 65/6 days.Then find how many days A will take to complete the work separately?​

A+B alternatively can do a work in 11 days

=> A work for 6 Days   & B work for  5 Days

B+A alternatively can do a work in 65/6 days

=> B work for 35/6 days  & A work for 5 Days

Let Say A's 1 day work = A

& B's 1 Day work = B

=> 6A + 5B  =  35B/6 + 5A

=> A = 5B/6

=> 6A = 5B

6A + 5B = 1

=> 6A + 6A = 1

=> 12A = 1

=> A = 1/12

A's 1 day work = 1/12

A will complete work in 12  Days separately
