दिलेले आहे:

A ची कार्यक्षमता = B ची कार्यक्षमता

C ची कार्यक्षमता = A ची कार्यक्षमता

वापरलेले सूत्र:

एकूण काम = कार्यक्षमता x वेळ

गणना:

प्रश्नानुसार:

A ची कार्यक्षमता = B ची कार्यक्षमता = C ची कार्यक्षमता

A, B आणि C 15 दिवसात काम पूर्ण करू शकतात.

⇒ 3 दिवस = (1 + 1 + 1) = कामाची 3 युनिट्स

⇒ 3 x 5 = 15 दिवस = 3 x 5 = 15 कामाचे युनिट

आता, C, A आणि B आळीपाळीने काम करू शकतात,

⇒ (1 + 1 + 1) = कामाची 3 युनिट्स = 3 दिवस

⇒ 3 x 5 = 15 एकके काम = 3 x 5 = 15 दिवस

∴ योग्य उत्तर 15 दिवस आहे.
