We are given a set of data for each hour as well as the average of the data. One of the data is made unreadable. To get this data, we simply have to use the formula for the average which is

average = (data1 + data2 + data3 + ... + datan) / n

where n is the total number of data

Since only data2 is made unreadable, the rest of the data are available and the value for data2 can be easily determined.
