Out of eight men, when a new man replaces the man weighing 65 kg, the average weight increases by 1.5 kg. What is the weight of the new man?
आठ व्यक्तियों के एक समूह में 65 किग्रा वजन वाले व्यक्ति के स्थान पर एक नया व्यक्ति आता है। इससे समूह का औसत वजन 1.5 किग्रा बढ़ जाता है। नए व्यक्ति का वजन कितना है?
Detailed Solution & Logic
77 kg / 77 किग्रा
Solution:
8 men की औसत में 1.5 kg की वृद्धि हुई।
कुल वजन में वृद्धि:
$8 \times 1.5 = 12$ kg
पुराने आदमी का वजन = 65 kg
नए आदमी का वजन:
65 + 12 = 77 kg
Answer: 77 kg / 77 किग्रा (Option 4)
