A के कार्य के घंटे = 5 घंटे/दिन
A एक कार्य को 8 दिनों में पूरा कर सकता है।
B के कार्य के घंटे = 6 घंटे/दिन
B उसी कार्य को 10 दिनों में पूरा कर सकता है।
प्रयुक्त अवधारणा:
M1 × D1 × H1 = M2 × D2 × H2
M = व्यक्ति; D = दिन ; H = घंटे
गणना:
प्रश्नानुसार:
⇒ A × 5 × 8 = B × 6 × 10
⇒ A/B = 3/2
कुल कार्य = A × 5 × 8 = 3 × 40 = 120 इकाई
लिया गया अभीष्ट समय = 120/{(3 + 2) × 8}
⇒ 120/40 = 3 दिन
∴ सही उत्तर 3 दिन है।
