Question

A, B and C can do a piece of work in 6 days, 12 days and 24 days respectively. In what time
will they altogether do it?​

Answer 1

Answer:

Step-by-step explanation:

If A can do a piece of work in n days, then A's 1 day's work = 1/n

(A+B+C)′s 1day's work=1/6 + 1/12 + 1/24 = 7/24

Formula: If A's 1 day's work = 1/n  , then A can finish the work in n days

So, all the three together will complete the job in

24/7 days=3 3/7 days

Answer 2

Answer:

3 whole 3/7 days

Step-by-step explanation:

A's one day work = 1/6

B's one day work = 1/12

C's one day work = 1/24

Hence, A, B and C's one day work = 1/6 + 1/12 + 1/24 = 7/24

Therefore, A, B and C will do the work altogether in 3 3/7 days.
