Detailed Solution
Download Solution PDFदिया गया है:
A, B से 40% अधिक कुशल है।
B कार्य को 36 दिनों में पूरा कर सकता है।
प्रयुक्त अवधारणा:
कुल कार्य = श्रमिक की दक्षता × श्रमिक द्वारा लिया गया समय
गणना:
मान लीजिये कि B की दक्षता 10a है
इसलिए, A की दक्षता
= 10a × 140%
⇒ 14a
इसलिए, कुल कार्य = 10a × 36
⇒ 360a
अब,
अगर वे दोनों कार्य करते हैं तो समय = 360a/(14a + 10a)
⇒ 360a/24a
⇒ 360/24
⇒ 15
∴ अभीष्ट उत्तर 15 दिन है।
