Answer 2

Answer:

The answer is:

Step-by-step explanation:

A can do 1/5th of work in 2 days

This implies that the total work is done by A in 2*5 = 10 days

A's one day work = 1/10

B can do 2/3rd work in 8 days

This implies that the total work is done by B in = 8*3/2 = 12 days

B's one day work = 1/12

Now, (A+B)'s one day work = 1/10 +1/12

=> 6 + 5 /60

=> 11 / 60

If A and B 's one day work = 11/60

They can complete the work together in = 60/11 days

=> 5  whole 5/11 days

OR

=> 60/11 days
