A और B मिलकर किसी कार्य को 50 दिनों में पूर्ण कर सकते हैं।
A, B से 40% कम कुशल है।
प्रयुक्त अवधारणा:
कुल कार्य = श्रमिकों की दक्षता × उनके द्वारा लिया गया समय
गणना:
माना B की दक्षता 5a है।
इसलिए, A की दक्षता = 5a × 60%
⇒ 3a
इसलिए, उनकी कुल दक्षता = 8a
कुल कार्य = 8a × 50
⇒ 400a
अब,
कार्य का 60% = 400a × 60%
⇒ 240a
अब,
अभीष्ट समय = 240a/3a
⇒ 80 दिन
∴ A अकेले कार्य करते हुए 60% कार्य को 80 दिनों में पूरा कर सकता है।
