टाकीचे एकूण काम किंवा क्षमता = LCM चे (1.5, 4.5, 6) = 18 युनिट
(A + B) = 18/1.5 = 12 युनिटची कार्यक्षमता
C = 18/4.5 = - 4 युनिटची कार्यक्षमता
(A - C) = 18/6 = 3 ची कार्यक्षमता
येथे, C = - 4 आणि (A - C) = 3, नंतर A = (4 + 3) = 7 युनिटची कार्यक्षमता
आता, B = (12 - 7) = 5 युनिटची कार्यक्षमता
तर, B संपूर्ण रिकामी टाकी = 18/5 = 3.6 तास = 3 तास 36 मिनिटांत भरू शकतो.
∴ बरोबर उत्तर 3 तास 36 मिनिटे आहे
