Question

A can do a piece of work in 10 days while B can do it in 15 days in how many days AandB can complete a work together?​

Answer 1

Step-by-step explanation:

A can do a piece of work in 1 day = 1/10

B can do a piece of work in 1 day = 1/15

A and B can complete a work together in 1 day =

1/10 + 1/15

= 3/30 + 2/30

= 5/30

= 1/6

hence, A and B can complete the work together

= 6 days
