Answer 1

your answer will be 64 because u have to add all four numbers up and divide by how many numbers there was and therefore there were 4 numbers and u get 64

Answer 2

Average is the total of x divide by number of x.
Here, we have,
x = 55, 64, 60, 61
number of x = 4
Total of x = 55 + 64 + 60 + 61 = 240
So, the average is,
240 / 4 = 60
