Answer:
103
Step-by-step explanation:
Unread pages = (a) 1 - 12; (b) 32 - 46; (c) odd numbered pages from 48 - 200
The number of pages in each range is:
(a) n₁ = 12 - 1 + 1 = 12
(b) n₂ = 46 - 32 + 1 = 15
(c) n₃ = 200 - 48 + 1 =153
Half the pages are odd-numbered.
153/2 = 76½.
200 and 48 are both even so there are more even-numbered pages in the range.
There are 77 even-numbered and 76 odd-numbered pages.
The total of unread pages is
12 + 15 + 76 = 103
