20 महिलाओं के एक समूह का औसत वजन 58.5 kg परिकलित किया गया और बाद में यह पता चला कि उनमें से एक महिला का वजन गलती से 35 kg पढ़ लिया गया था, जबकि उसका वास्तविक वजन 65 kg था, 20 महिलाओं के समूह का वास्तविक औसत वजन कितना होगा?
Detailed Solution & Logic
60 kg
Incorrect total = $ 20 \times 58.5 = 1170$
Error = 65 - 35 = 30
Correct total = 1170 + 30 = 1200
Actual average = $ \dfrac{1200}{20} = 60$
Answer = 60kg
