Answer:
Let,
total work is X
In the case of A,
In 6 days he does X unit
in 1 day he does X/6 unit
In the case of B,
In 9 days he does X unit
in 1 day he does X/9 unit
together they do in 1 day =(x/6)+(x/9)=5x/18
So, 5x/18 unit is done together in 1 day
X unit is done together in X /(5x/18)=18x/5x=18/5 day
