Question : The average of nine numbers is 20. If two of these numbers are removed, then the average becomes 18. What is the sum of the two numbers that are removed?
Option 1: 56
Option 2: 58
Option 3: 54
Option 4: 52
Answer (1)
Correct Answer: 54
Solution :
An average of 9 numbers = 20
⇒ the sum of 9 numbers = 20 × 9 = 180
After two numbers are removed, the total number is 7
The new total is 18 × 7 = 126
⇒ the sum of 2 numbers removed = 180 – 126 = 54
Hence, the correct answer is 54.
