Question
The average of five numbers is 27. If one number is excluded, the average becomes 25. The excluded number is ?35552545
Solution
Step 1: The average of five numbers is 27. So, the total sum of these five numbers is 27 * 5 = 135.
Step 2: If one number is excluded, the average becomes 25. So, the total sum of the remaining four numbers is 25 * 4 = 100.
Step 3: The excluded number is the difference between the total sum of the five numbers and the total sum of the remaining four numbers. So, the excluded number is 135 - 100 = 35.
