Solution
The correct option is B 1,190 Total number of pages before changes = 10,546
Total number of pages after changes = 8,356
Reduced pages = Total number of pages before changes – Number of pages after changes
= 10,546 – 8,356
Let's subtract the numbers using vertical subtraction.
Vertical subtraction is a method of subtracting where the numbers are lined up in columns according to their place values.
Therefore, the number of reduced pages in the revised version is 1,190.
