heya mate here is your answer
A's 6days work = 1
B's 9days work = 1
one day work of A = 1/6
one day work of B = 1/9
A and B together's one day work
= 1/6 + 1/9
= 9+6 /54
=15/54
number of days taken by A and B together to complete their work = 54/15
A's 6days work = 1
B's 9days work = 1
one day work of A = 1/6
one day work of B = 1/9
A and B together's one day work
= 1/6 + 1/9
= 9+6 /54
=15/54
number of days taken by A and B together to complete their work = 54/15
it's wrong
