Answer:
48 pages
Step-by-step explanation:
Total no of pages = 196 pages
No of pages read on last day = 52 pages
Subtract the amount she read on the fourth day from the total no of pages.
196 pages - 52 pages = 144 pages
No of pages on the first three days = 144 pages
No of pages read each day = 144/3 = 48 pages
