On Thursday, Wesley read ⁵₈ of a novel. On Friday, he read 10 pages of the novel. On Saturday, he read ⁴₇ of the remaining book leaving 60 pages unread.

1. Find the number of pages read on Saturday.
2. 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 - 4 u
= 3 u

3 u = 60

1 u = 60 ÷ 3 = 20

Number of pages that Wesley read on Saturday
= 4 u
= 4 x 20
= 80

(b) 
Working backwards.

Number of pages unread after reading on Friday
= 7 u
= 7 x 20
= 140

Total number of pages in the novel = 8 p

Number of pages unread after reading on Thursday 
= 8 p - 5 p
= 3 p

3 p = 10 + 140
3 p = 150

1 p = 150 ÷ 3 = 50

Total number of pages in the novel
= 8 p
= 8 x 50
= 400

Answer(s): (a) 80; (b) 400
