Question

The person A can do a piece of work in 12 days while the person B can do it in 18 days. In how many days Will they do it together​

Answer 1

Answer:

36/5 days or 7 (1/5)

Step-by-step explanation:

One day's work by A = 1/12

One day's work by B = 1/18

Together they can do work in one day = (1/12) + (1/18) = (5/36)

So, they together complete the work = 1/(5/36) = 36/5 days
