Answer:

hey mate your answer is here

Step-by-step explanation:

work done by a and b to finish the work = 13 days

time time taken by a alone to finish the work = 30 days

A+B 1 days work= 1/3

Alone A days work= 1/20

A+B 1 days work - A 1days work

1/3 -1/20

20- 3/60

17/60 = 3 upon 19 by 17 ANS
