A, B और C एक कार्य को क्रमश: 11 दिन, 20 दिन और 55 दिन में कर सकते हैं।

गणना:

कुल कार्य = (11, 20 और 55) का लघुत्तम समापवर्त्य = 220

 A की क्षमता = 220/11 = 20 

B की क्षमता = 220/20 = 11

C की क्षमता = 220/55 = 4

पहले दिन का कार्य = (20 + 11) = 31

दूसरे दिन का कार्य = (11 + 4) = 15

2 दिनों का कार्य = 31 + 15 = 46

कार्य करने के लिए आवश्यक कुल जोड़े दिन

220/46

4 + 36/46

इसलिए, 4 × 2 = 8 दिन और शेष कार्य = 36

अगले दिन 36 में से 31 और शेष 5 10वें दिन किए जाएंगे 

5/15 = 1/3

तो, कुल दिन = 9 + 1/3

∴ कुल अभीष्ट दिन = 9 + 1/3 दिन
