Note: Consider 84 instead of 83 because the value of x is a decimal value of 83 which is not possible.
Given:
Compound ratio of 7:5 and 8:x is 84:60.
To find:
The value of x.
Solution:
Compound ratio of 7:5 and 8:x is 84:60.

Based on the calculations, the number of books that were bought by Hugh are 4 books.
<h3>How to calculate the number of books?</h3>
In order to determine the number of books that were bought by Hugh, we would substitute the value of the number of magazines into the given equation and then evaluate as follows:
3.95m + 8.95b = 47.65
3.95(3) + 8.95b = 47.65
11.85 + 8.95b = 47.65
8.95b = 47.65 - 11.85
8.95b = 35.8
b = 35.8/8.95
b = 4.
In conclusion, the number of books that were bought by Hugh are 4 books.
