Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 27.
Given: Average of 9 consecutive odd numbers = 27
⇒ Middle number = 27
⇒ Numbers = 9 odd numbers centered at 27
Add previous and next odd numbers: 2 more numbers
Now total = 11 consecutive odd numbers
Average of consecutive odd numbers = middle number = still 27
