On Thursday, Jenson read
25 of a novel. On Friday, he read 46 pages of the novel. On Saturday, he read
57 of the remaining book leaving 34 pages unread.
- Find the number of pages read on Saturday.
- Find the total number of pages in the novel.
(a)
Number of remaining unread pages after reading on Friday = 7 u
Number of remaining unread pages after reading on Saturday
= 7 u - 5 u
= 2 u
2 u = 34
1 u = 34 ÷ 2 = 17
Number of pages that Jenson read on Saturday
= 5 u
= 5 x 17
= 85
(b)
Working backwards.
Number of pages unread after reading on Friday
= 7 u
= 7 x 17
= 119
Total number of pages in the novel = 5 p
Number of pages unread after reading on Thursday
= 5 p - 2 p
= 3 p
3 p = 46 + 119
3 p = 165
1 p = 165 ÷ 3 = 55
Total number of pages in the novel
= 5 p
= 5 x 55
= 275
Answer(s): (a) 85; (b) 275
