Answer:

10/3 day

Step-by-step explanation:

B can complete that in 10 days. It means,

In 1 day. B can do = 1/10  of work

Whereas,  A is two time faster than B, so,

In 1 day A can do = 2(1/10) =1/5  of work

If they work together,  

In 1 day (A+B) can do = 1/10 + 1/5 of work

In 1 day (A + B)  can do = 3/10 of work

In 10/3 day (A + B) can do = 1 of whole work

1 of whole work implies to "total work or whole work"
