Q8DSSSB TGT Computer Science, 7 Feb 2024, Shift 2 (12:30 PM)
The average age of 40 students is 21 years. It was observed that while calculating the average age, the age of a student was taken as 20 years instead of 30 years. What will be the correct average age?

  2. B21.22 years
  3. C12.12 years
  4. D23.84 years
Show answerHide answer

Correct answer: (A) 21.25 years

Explanation

The total age rises by 30 − 20 = 10 years, so the average rises by 10/40 = 0.25. Correct average = 21 + 0.25 = 21.25 years.
