The average weight of a group of 20 women was calculated as 58.5 kg and it was later discovered that the weight of one of the women was read as 35 kg, whereas her actual weight was 65 kg. What is the actual average weight of the group of 20 women?
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
