It should be a multiple of 13 so, 468 among the options.

96 pages were unread
so on second week have 5/9

So unread pages = 1 - 5/9 = 4/9
96*9/4 = 216

then, on first week unread pages were 216
total pages = 216*13/6= 468

So answer is 468

Given 96 left..
Lets Calculate on remaining pages for 2nd week then 1st week based on given data.
its ratio is 4/9
So..4x/9=96 this gives x=216 wich is 2nd week total.
Where as first week ratio is 6x/13=216 wich gives 468.

the option which is a multiple of 9 and 13 will be the answer and i think this is the fastest method to solve this question

let total be 1

1st week- 7/13
remaining part 1-7/13= 6/13

2nd week- 5/9(6/13)= 10/39
remaining- 6/13-10/39=8/39

as given 8/39=96 =>468

book read = 7/13 + [(5/9)*(1-(7/13))] = 31/39 th part

book unread = 1-(31/39) = 8/39 th part

given book unread=96 so
96=8/39 th part 
total =468

Ist week remaining pages 6/13 of total
2nd W.r = 4/9

Remaining pages = 96=6/13 of 4/9 of total remaining pages
Hence remaining pages = (96x13x9)/(6x4)=468

Let the total book pages are X.
Then Unread page in first week was 6X/13
so after second week unread pages is 96
6X/13(4/9) = 96
x = 468

let 1
1-7/13=6/13
let remaining book for second week is 1
1-5/9=4/9
then 4part =96
then 9 part=216=1 means 6/13
so 6part=216
so 13 part=36*13=468
