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 work​

Answer 1

Answer:

10 days

Step-by-step explanation:

A done work in 8 days

B done work in 12 days

Now they do that work together

so half effort of A & half of B

A= 8/2=4

B=12/2=6

4+6=10

Answer 2

solve = we have.

= if total work = 1 unit

= A's 1 days work = 1/8 unit's .

= B's 1 days work = 1/12 unit.

Then,

= x ( 1/8 + 1/12) = 1

= x ( 3+2 / 24 )

= x ( 24 /5) = 4.8 days - answer.
