Work Calculation
A can complete the work in 12 days.
B can complete the work in 8 days.
C can complete the work in 10 days.
A's 1 day work = 1/12
B's 1 day work = 1/8
C's 1 day work = 1/10
A + B + C's 1 day work =
= (1/12 + 1/8 + 1/10)
= (10 + 15 + 12) / 120
= 37/120
So, A + B + C will complete the full work in:
= 120 / 37 days
≈ 3.24 days
✅ Final Answer: 120/37 days or approximately 3.24 days
