82 विद्यार्थियों की एक कक्षा का औसत वजन 62.5 kg है। यदि आधे विद्यार्थियों का औसत वजन 83.6 kg है, तो कक्षा के शेष विद्यार्थियों का औसत वजन (kg) में ज्ञात कीजिए।
Detailed Solution & Logic
Correct Answer:
41.4
Total weight of 82 students
$= 82 \times 62.5$
= 5125 kg
Weight of half students (41 students)
$= 41 \times 83.6$
= 3427.6 kg
Weight of remaining 41 students
= 5125 - 3427.6
= 1697.4 kg
Average weight of remaining students
$= \dfrac{1697.4}{41}$
Answer = 41.4
