Questions & Step-by-Step Solutions

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.
  • Average Calculation – Understanding how to calculate the average of a set of numbers by using the total sum and the number of elements.
  • Subtraction of Known Values – Using known values to find the total of remaining numbers by subtracting a specific number from the total.
  • Division for Average – Calculating the average of the remaining numbers by dividing the total of those numbers by their count.
