Answers
Answer:
2prople do he work in 8days
8×2=16
one person can do the work in 16days
so 3 people can do the work in
16/3=5.3333
approx =5 days
pl. Mark as brainliest and follow me
The correct question is-
Anil and Babu can do a job in 8 days. Babu and Charan can do the same job in 12 days. Anil, Babu and Charan can do the job in 6 days. In how many days Anil and Charan can complete the job?
The total amount of time taken to complete the work by Anil and Charan together = 8 days.
Given:
- Anil and babu can do a job in 8 days.
- Babu and Charan can do the same job in 12 days.
- Anil, Babu and Charan can do the job in 6 days.
To find: In how many days can Anil and Charan complete the job
Step by step explanation:
→ Amount of work Anil and Babu can do in 1 day = 1/8.
→ Amount of work Babu and Charan can do in 1 day = 1/12.
→ Amount of work Anil, Babu, and Charan can do in 1 day = 1/6.
We need to find the amount of work done by Amit and Charan in 1 day
= Amount of work Anil do in 1 day + Amount of work Charan do in 1 day.
⇒ Now, we need to find amount of work done by Amit for 1 day = Amount of work done by all 3 - Amount of work done by Babu and Charan
= 1/6 - 1/12
Taking LCM of 6 and 12 = 12 and multiplying to make the required denominator
= (2 - 1)/12
= 1/12
→ Amount of work by Amit in 1 day = 1/12
⇒ Now, we need to find amount of work done by Charan for 1 day = Amount of work done by all 3 - Amount of work done by Anil and Babu
= 1/6 - 1/8
Taking LCM of 6 and 8 = 24 and multiplying to make the required denominator
= (4 - 3)/24
= 1/24
→ Amount of work by Charan in 1 day = 1/24
The amount of work done by Anil and Charan in 1 day = 1/12 + 1/24
= (2 + 1)/24
= 3/24
= 1/8
So, the total amount of time taken to complete the work by Anil and Charan together = 8 days.
