Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFदिलेले आहे:
(राजा + रॉकी) मिळून रंगकाम पूर्ण करू शकतात = 5 दिवसांत
वापरलेले सूत्र:
एकूण काम = कार्यक्षमता × वेळ
गणना:
प्रश्नानुसार:
⇒ (राजा + रॉकी) × 2 + राजा × 4 = (राजा + रॉकी) × 5
⇒ राजा × 4 = (राजा + रॉकी) × 3
⇒ राजा × 1 = रॉकी × 3
⇒ राजा/रॉकी = 3/1
एकूण काम = (राजा + रॉकी) × 5
⇒ (3 + 1) × 5 = 4 × 5
⇒ 20 एकक
रंगकाम पूर्ण करण्यासाठी रॉकीने एकट्याने घेतलेला वेळ = 20/1 = 20 दिवस
∴ 20 दिवस हे योग्य उत्तर आहे.
