On calculation means (average) of 15 numbers was 64. One of the number 24 was misread as 34. What is the correct means?
حساب میں 15 نمبروں کا مطلب (اوسط) 64 تھا۔ 24 نمبروں میں سے ایک کو 34 کے طور پر غلط پڑھا گیا تھا۔ صحیح مطلب کیا ہے؟
- 63.3
- 73.3
- 53.3
- 43.3
Explanation
63.3 is the correct answer
total number 15 ×64=960 24 was misread as 34 so actual no is 10 more so subtract 10 from 960 which is 960-10 = 950 now divide 950 by total number which is 15 950/15 = 63.33 is correct answer
