B. 16.5 Hours
C. 17 Hours
D. 15.5 Hours

View Answer
B. 16.5 Hours

Arif can Read 39 pages in 30 minutes.
How much time is required to read 1287 pages?
39 page read time = 30 minute
01 page read time=30/39=0.76923 minute
1287 pages read time=0.769*1287=990 minute
990 conversion into hours = 990/60 = 16.5 Hours

Another Simple Explanation:

39 pages for a half hour equals 78 pages per hour and if the book has 1287 pages then 1287 pages divided by 78 pages per hour gives you 16.5.
