The average of 5 consecutive odd natural numbers is 27. Previous 5 consecutive odd natural numbers to these 5 odd natural numbers are also included. What will be the average of newly added numbers?
Show answer & explanation
Correct answer: B
Explanation
Given:
Average of 5 consecutive odd numbers = 27
According to the formula:
Average of consecutive numbers = Middle number
The 5 consecutive odd numbers:
23, 25, 27, 29, 31
The 5 consecutive odd numbers preceding these:
13, 15, 17, 19, 21
Average of the newly added numbers
= (13 + 15 + 17 + 19 + 21) / 5
= 85 / 5
= 17
