GMAT Club Official Solution:
Let the originally planned time be N days. Let each machine’s rate be r jobs per day.
Planned total work = 3 * r * N.
Let the total off days be:
Alpha = A
Beta = B
Gamma = C
Actual completion time is N + 4 days, so actual work done is:
r * ((N + 4 - A) + (N + 4 - B) + (N + 4 - C)) =
= r * (3(N + 4) - (A + B + C))
Set actual work equal to planned work:
3 * r * N = r * (3(N + 4) - (A + B + C))
3N = 3(N + 4) - (A + B + C)
A + B + C = 12
Given:
A = B + 3
B = C + 3
So A = C + 6
Then:
A + B + C = (C + 6) + (C + 3) + C = 3C + 9 = 12
C = 1
Answer: A.

Since the rates are constant for Alpha, Beta and Gamma = a.
Let d be the actual number of days taken to complete the work.
So, the total work = 3a*d
Let x be the number of days gamma has taken off.
The number of days off for Beta = (x+3) .
The number of days off for Alpha = (x+6).
Adding all off days = x + (x+3) + (x+6)
= (3x+9) days
The number of units completed in this off days equals the work completed in 4 days.
since the number of days taken is 4 days later than actual.
(3x+9)*a = 3a*4
3x+9 = 12
x=1
Gamma has taken 1 day off.
option A
