From the statement it is determined that the maximum limit is 100 and the lower limit is 0. At the same time there is an average of 85 that is closer to the upper limit than the lower limit, therefore the distribution will tend to occur to the left .

This will mean that people will begin to surround the average of 85 and that those who are 60, will be more than those who are below 50, and these 50 will be more than those who are by 40 and so on.
