Novel N has 71 fewer pages than Novel P, and Novel Q has 36 more pages than Novel P. If Novel N and Novel P have a total of 151 pages,
- how many pages does Novel P have?
- how many pages does Novel Q have?
(a)
Number of pages that Novel N has = 1 u
Number of pages that Novel P has = 1 u + 71
Number of pages that Novel Q has = 1 u + 71 + 36
Total number of pages that Novel N and Novel P have
= 1 u + 1 u + 71
= 2 u + 71
2 u + 71 = 151
2 u = 151 - 71
2 u = 80
1 u = 80 ÷ 2 = 40
Number of pages that Novel P has
= 1 u + 71
= 40 + 71
= 111
(b)
Number of pages that Novel Q has
= 1 u + 71 + 36
= 111 + 36
= 147
Answer(s): (a) 111; (b) 147
