    Verified Answer
    A can do a work in 8 days, B can do a work in 7 days, C can do a work ...
    Let work rate of A be a
    Let work rate of B be b
    Let work rate of C be c
    So,
    a + b = 1/8 
    b + c = 1/12
    a + b + c = 1/6
    Sub Eq(1) in Eq(3), we get
    c = 1/24
    Sub value of c in Eq(2), we get
    b = 1/24
    Sub value of b in Eq(1), we get
    a = 1/12
    So,
    a + c = 1/8
    So, A and B will complete the work in 8 days

    A can do a work in 8 days, B can do a work in 7 days, C can do a work ...
    Understanding the problem:
    - A can do the work in 8 days.
    - B can do the work in 7 days.
    - C can do the work in 6 days.
    - They work on alternate days - A on the first day, B on the second day, and C on the third day.

    Calculating the fraction of work done each day:
    - A can do 1/8 of the work in a day.
    - B can do 1/7 of the work in a day.
    - C can do 1/6 of the work in a day.

    Calculating the total work done in 3 days:
    - In 3 days, the total work done by A, B, and C is 1/8 + 1/7 + 1/6 = 7/168.

    Determining when they will finish the work:
    - Since they complete 7/168 of the work in 3 days, they will finish the work in 24/7 days.
    - 24/7 days is equivalent to 3 full days and a little more.
    - Therefore, they will finish the work on the 4th day.

    Conclusion:
    - They will finish the work on the 4th day.
