The average of the last three numbers is 58 if the average of the five numbers in a list is 54. the average of the first two numbers is 48.
What is average?
It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.
It is given that:
The average of the five numbers in a list is 54. and the average of the first two numbers is 48.
54 = sum of the five numbers/5
54x5 = sum of the five numbers
270 = sum of the five numbers
48 = sum of the two numbers/2
48x2 = sum of the two numbers
96 = sum of the two numbers
Sum of three numbers = 270 - 96
Sum of three numbers = 174
The average of the last three numbers = 174/3 = 58
Thus, the average of the last three numbers is 58 if the average of the five numbers in a list is 54. the average of the first two numbers is 48.
