Question: If the average of 4 numbers is 50 and one number is 60, what is the average of the remaining three numbers?

Options:

Correct Answer: 45

Solution:

Total of 4 numbers = 4 * 50 = 200. Remaining total = 200 - 60 = 140. Average of remaining = 140 / 3 = 46.67.

If the average of 4 numbers is 50 and one number is 60, what is the average of the remaining three numbers?

If the average of 4 numbers is 50 and one number is 60, what is the average of the remaining three numbers?

Step 1: Understand that the average of 4 numbers is 50.
Step 2: Calculate the total of the 4 numbers by multiplying the average by the number of numbers: 4 * 50 = 200.
Step 3: Identify that one of the numbers is 60.
Step 4: Subtract the known number (60) from the total (200) to find the total of the remaining 3 numbers: 200 - 60 = 140.
Step 5: To find the average of the remaining 3 numbers, divide the total of the remaining numbers (140) by 3: 140 / 3 = 46.67.
