If the longest book has 294 pages, then the length of the other 6 books is 252 pages
How to determine the mean length?
The given parameters are:
- Mean length of 7 books = 258 pages
- Longest book = 294 pages
The mean is calculated using:
Mean = Sum/Count
So, we have:
Sum/7 = 258
Multiply both sides by 7
Sum = 1806
Subtract the length of the longest book to determine the sum of the other 6 books
6 books = 1806 - 294
Evaluate
6 books = 1512
Their mean is then calcuated using:
Mean = 1512/6
Evaluate
Mean = 252
Hence, the length of the other 6 books is 252 pages
