Novel Q has 58 fewer pages than Novel R, and Novel S has 18 more pages than Novel R. If Novel Q and Novel R have a total of 164 pages,
- how many pages does Novel R have?
- how many pages does Novel S have?
(a)
Number of pages that Novel Q has = 1 u
Number of pages that Novel R has = 1 u + 58
Number of pages that Novel S has = 1 u + 58 + 18
Total number of pages that Novel Q and Novel R have
= 1 u + 1 u + 58
= 2 u + 58
2 u + 58 = 164
2 u = 164 - 58
2 u = 106
1 u = 106 ÷ 2 = 53
Number of pages that Novel R has
= 1 u + 58
= 53 + 58
= 111
(b)
Number of pages that Novel S has
= 1 u + 58 + 18
= 111 + 18
= 129
Answer(s): (a) 111; (b) 129
