It is one more than 129, or one fewer than 131. Alternatively, it can be considered as 10 more than 120 or 10 fewer than 140. There are other variations on the theme. Another approach is to consider it as 10 times 13 or one tenth of 1300. Or double 65 or half of 260.

The phrase "q fewer lines than 10" suggests that a certain quantity, denoted as "q," represents the number of lines that are less than 10. This means that if you have 10 lines, you would subtract "q" from 10 to determine the actual number of lines, resulting in a total of (10 - q) lines. The value of "q" must be less than 10 for the operation to make sense in this context.
