A, B तथा C अकेले कार्य करके एक कार्य को क्रमशः 9, 12 तथा 18 दिनों में पूरा कर सकते हैं। A, B तथा C मिलकर उसी कार्य को कितने दिनों में पूरा कर सकते हैं?
Answer और ExplanationAnswer and explanation
Answer: (C) 4
कुल कार्य = LCM(9, 12, 18) = 36 units
A = 4, B = 3, C = 2 units/day ⇒ मिलकर = 9 units/day
समय = 369 = 4 दिन
✓
A, B और C मिलकर 4 दिन लेंगे।
Total work = LCM(9, 12, 18) = 36 units
A = 4, B = 3, C = 2 units/day ⇒ together = 9 units/day
Time = 369 = 4 days
✓
A, B and C together take 4 days.
