Correct answer: (C) 5 5/7
Taking total work = 60 units, daily rates: Rajeshwar 5, Vikram 10, Tiger 4. First 2 days (all three): 38 units. Last 3 days: Tiger alone does 3×4=12 units. Remaining 60−38−12=10 units done by Vikram+Tiger (14/day) in 10/14=5/7 day. Total = 2+5/7+3 = 5 5/7 days.

सही उत्तर: (C) 5 5/7
कुल कार्य = 60 इकाई मानें, दैनिक दर: राजेश्वर 5, विक्रम 10, टाइगर 4। पहले 2 दिन (तीनों साथ): 38 इकाई। अंतिम 3 दिन: टाइगर अकेले 3×4=12 इकाई करता है। शेष 60−38−12=10 इकाई विक्रम+टाइगर (14/दिन) द्वारा 10/14=5/7 दिन में पूर्ण होती है। कुल = 2+5/7+3 = 5 5/7 दिन।
