राजेश्वर एक कार्य को 12 दिनों में, विक्रम 6 दिनों में और टाइगर 15 दिनों में पूरा कर सकता हैं। वे सभी एक साथ कार्य करना शुरू करते हैं, लेकिन राजेश्वर 2 दिन बाद कार्य करना छोड़ देता है और विक्रम कार्य पूरा होने से 3 दिन पहले कार्य करना छोड़ देता हैं। कार्य कितने दिनों में पूरा होगा?
Detailed Solution & Logic
\(5\frac{5}{7}\)
$ R=\dfrac{1}{12}, V=\dfrac{1}{6}, T=\dfrac{1}{15} $
Total time = $ x $
$ \dfrac{2}{12}+\dfrac{x-3}{6}+\dfrac{x}{15}=1 $
$ 7x=40 $
$ x=\dfrac{40}{7}=5\dfrac{5}{7} $
$ {5\dfrac{5}{7}} $
