The average of 6 numbers is 18. If two numbers 14 and 22 are removed, what is the new average of the remaining numbers?
Show answer & explanation
Correct answer: A
Explanation
Given:
Number of numbers = 6
Average = 18
Numbers removed = 14, 22
Formula:
Total = Average × Number
Total = 6 × 18 = 108
Sum of removed numbers = 14 + 22 = 36
Remaining sum = 108 − 36 = 72
Remaining numbers = 4
New average = 72 / 4 = 18
