Answer»

Step-by-step EXPLANATION:

In 10 days A + B can so = 1 work

In 1 DAY A+B can do = 1/10 work

In 15 days A can do = 1 work

In 1 day A can do = 1/15 work

Let in x days B can do = 1 work

so in 1DAY B can do 1/x work

In 1 day A+B can do = 1/10 work

1/15 + 1/x = 1/10

1/x = 1/10 - 1/15

1/x = 1/30

x = 30
