Answer:
The page numbers on the opposite side are (6-1) and (27+1) which is 5 and 28.
The number of pages is twice the (6+(27-1))/2
Therefore the number of pages = 2 xx (6+(27-1))/2
= 32.
The other way to get this is there are 5 more pages before 6, therefore there should be 5 more pages after 27 also. Therefore the number of pages = 27+5 = 32
