How to determine the number of pages or juz!
If someone asks us, coca page 9 juz of the Quran begins (for example)?
So just need to do a little mathematical calculation, and it is:
9 Gus:
9-1 = 8
8 + 8 = 16
16 is added to the end of the 2-ku = 162
162 Page 9 juz.
And so you can find the beginning of any page of any juz.
For example 15 juz.
15-1 = 14
14 + 14 = 28
28 is added to the end of the 2-ku = 282
Page 15 juz 282.
