Question

A and B working together they can complete in 8 day and A along can complete that work in 12 days then B along can complete in how many days
​

Answer 1

Answer:

24 days

Step-by-step explanation:

The one-day work of A and B is

$\frac{1}{A}+\frac{1}{B} = \frac{1}{8}$ (Since A and B working together can complete the work in 8 days)

The one day work of A is

$\frac{1}{A} = \frac{1}{12}$ (Since A alone can complete the work in 12 days)

Therefore the one-day work of B will be

$\frac{1}{B}= \frac{1}{8}-\frac{1}{12}= \frac{1}{24}$

Therefore, B alone can complete the work in 24 days.
