दिया 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।
