A and B take M days to complete a task together if A takes 27 days more than A and B to complete the task alone. And if B takes 3 days more than A and B can do the job alone, what is the value of M?​

Answer 1

Answer:

9 days.

hope it helps

Step-by-step explanation:

As per given data

1/x=1/(x+27)+1/(x+3)

1/x=(x+3+x+27)/(x+27)(x+3)

X^2+30x+81=2x^2+30x

X^2=81

X=9

so A&B can together do the work in 9 days
