Question
A can complete a work in 20 days, B can complete it in
25 days, and C can complete it in 30 days. If all three work together, how long will it take to finish the work?Solution
Work done by A in one day = 1/20. Work done by B in one day = 1/25. Work done by C in one day = 1/30. Combined work in one day = (1/20 + 1/25 + 1/30). Finding a common denominator (LCM = 300): = (15 + 12 + 10) / 300 = 37/300. Time taken to finish the work together = 300/37 ≈ 8.1 days. Correct option: d) 8 days
