Carl and Bob can demolish a building in 6 days, Anne and Bob can do it in 3, Anne and Carl in 5. How many days does it take all
nata0808 [166]

Answer:

  • 59/20 days or 2.95  days

Step-by-step explanation:

Let Carl do the job in c days, Anne- in a, and Bob in b days

Then the portion of job they can do is 1/c, 1/a and 1/b

<u>As per given we have below equations:</u>

  • 1/c + 1/b= 1/6
  • 1/a + 1/b = 1/3
  • 1/a + 1/c = 1/5

<u>Sum of all 3 equations gives us:</u>

  • 2(1/a + 1/b + 1/c) = 1/6 + 1/3 + 1/5
  • 2(1/a + 1/b + 1/c) = 5/30 + 10/30 + 6/30
  • 2(1/a + 1/b + 1/c) = 21/30
  • 2(1/a + 1/b + 1/c) = 7/10
  • 1/a + 1/b + 1/c = 7/20

It means all three together can complete 7/20 of the job in one day

<u>The rest of the job is done by Anne and Bob:</u>

  • 1 - 7/20 = 13/20

<u>As Anne and Bob can do 1/3 of the job in one day, they need time to complete the rest:</u>

  • 13/20:1/3 = 39/20

<u>Add 1 day to this to find overall time:</u>

  • 1 + 39 /20 = 59/20 days or 2.95  days
