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"

Answer:
A=2 (B)

B = 10 days
=> A = (2*10) days
=> A= 20 days
