P और Q मिलकर एक कार्य को 6 दिनों में पूरा कर सकते हैं।
P अकेले कार्य को 18 दिनों में पूरा कर सकता है।
प्रयुक्त सूत्र:
कुल कार्य = मनुष्य × दक्षता
गणना
P का 1 दिन का कार्य = 1/18
(P + Q) का 1 दिन का कार्य = 1/6
Q का 1 दिन का कार्य = 1/6 – 1/18 = 1/9
अतः Q अकेले कार्य को 9 दिनों में पूरा कर सकता है।
Shortcut Trick
Q = [(P + Q) × P] /(P + Q - P)
Q = (18 × 6)/(18 - 6)
Q = 9 दिन
