What will be the average of all the even numbers between 11 and 29?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 20.
Even numbers between 11 and 29 are 12, 14, 16, 18, 20, 22, 24, 26, 28
We know that,
Average = Sum of observations/Number of observations
Average = (12 + 14 + 16 + 18 + 20 + 22 + 24 + 26 + 28)/9
⇒ 180/9 = 20
