Answer 2

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
