- Seems to be question is wrong. Total days are coming in fractions
A's one day work would be 1/12
B's one day work would be 1/24
C's one day work would be 1/6
A, B and C's one day work would be 1/12 + 1/24 + 1/6 = 7/24.
A, B and C's together finish their work in 24/7 Days - 12 years agoHelpfull: Yes(62) No(5)
- A's one day work = 1/12
B's one day work = 1/24
C's one day work = 1/6
A, B and C's one day work = 1/12 + 1/24 + 1/6 = 7/24.
Time taken by A, B and C's together to finish their work = 24/7 Days - 12 years agoHelpfull: Yes(18) No(2)
- LCM(12,24,6)=24(articles)
A alone can do work in 12 days & he can do 2 articles per day
B alone can do it in 24 days& 1 article per day
c alone can do it in 6 days & 4 articles per day
all together complete 7 articles per day..
to complete 24 articles=24/7=3.4days - 12 years agoHelpfull: Yes(6) No(0)
- 3(3/7)days they take to finish the job together.
In 1 day, A work = 1/12
In 1 day, B work = 1/24
In 1 day, A work = 1/6
In 1 day, A,B& C work = 1/12 + 1/24 + 1/6 = 7/24.
Time taken by A,B,C to finish work = 24/7 ==> 3*(3/7) days - 12 years agoHelpfull: Yes(4) No(1)
- A's 1 day work = 1/12
B's 1 day work = 1/24
C's 1 day work = 1/6
(A+B+C)'s 1 day work=1/12+1/24+1/6=2+1+4/24=7/24
since time and work is inversely proportional the whole work is done in 24/7 days i.e.approximately 3.4 days

- A does 1 day work in 1/12 ; B does 1 day work in 1/24 ; C does 1 day work in 1/6
A+B+C = 1/12 + 1/24 + 1/6 = 7/24
completes the wrk in 24/7=3.42 days - 11 years agoHelpfull: Yes(2) No(0)
- 1/12+1/24+1/6=7/24
ans=24/7 - 11 years agoHelpfull: Yes(2) No(0)
- Work done per day by A, B and C together = 1/12 + 1/24 + 1/6 = 7/24
Therefore, days taken to complete the work together = 24/7 days - 12 years agoHelpfull: Yes(1) No(1)
- A can do a work in 1/12 days
B can do a work in 1/24 days
C can do a work in 1/6 days
A,B,C can do a work in 1/12+1/24+1/6 days
so together they can do in 24/7 days - 11 years agoHelpfull: Yes(1) No(0)
- A---IN 12DAYS =1/12
B---IN 24DAYS =1/24
C---IN 6DAYS =1/6
WITH TOGETHER=1/12+1/24+1/6=7/24 - 11 years agoHelpfull: Yes(1) No(7)
- 1/12+1/24+1/6=7/24 compllete in 24/7 days
- 11 years agoHelpfull: Yes(1) No(0)
- A's 1 day work = 1/12
B's 1 day work = 1/24
C's 1 day work = 1/6
(A+B+C)'s 1 day work=1/12+1/24+1/6=7/24
so the whole work is done in 24/7 days or 3.4 days - 12 years agoHelpfull: Yes(0) No(0)
- A's one day work=1/12
B's one day work=1/24
c's one day work=1/6
together work for one day=1/12+1/24+1/6=7/24
so together can complete the work in 24/7 days

- 24/7 ≈ 3.5 days required
if x is the total amount of work to be done
the A will do x/12, B will do x/24, C will do x/6 in a day
so if the work together x/12 + x/24 + x/6 = x*7/24 will do in a day - 11 years agoHelpfull: Yes(0) No(1)
- 12+24+6/3=32/3
10.6 - 10 years agoHelpfull: Yes(0) No(3)
- a=12
b=24
c=6 lcm=24 a+b+c=7days so,total work=24 a+b+c=24/7
ANS=24/7days - 10 years agoHelpfull: Yes(0) No(0)
