Answer:
72
Step-by-step explanation:
To find the mean of the numbers
We count the numbers in the given question
Let n be the count of those numbers
Hence n = 7
Let us calculate the sum of all the numbers
Sum = 81 +74 +69 +73+91+55+61
Then the mean of the numbers is Total sum divided by the count of the numbers
Hence ,mean = Sum / n
= 504/7
= 72
mean is 72
