Question

A and B separately can do a piece of work in 8 days and 12 days respectively. How much time will they take together to do the same time

Answer 1

Answer:

4 4/5 days

Step-by-step explanation:

A's one day work = 1/8

B's one day work = 1/12

One day work when they work together = 1/8 + 1/12

= 5/24

Time they will take together to finish the work = (1)/(5/24)

= 24/5 days

$4 \times\frac{4}{5} \: days$
