Novel V has 32 fewer pages than Novel W, and Novel X has 20 more pages than Novel W. If Novel V and Novel W have a total of 154 pages,
- how many pages does Novel W have?
- how many pages does Novel X have?
(a)
Number of pages that Novel V has = 1 u
Number of pages that Novel W has = 1 u + 32
Number of pages that Novel X has = 1 u + 32 + 20
Total number of pages that Novel V and Novel W have
= 1 u + 1 u + 32
= 2 u + 32
2 u + 32 = 154
2 u = 154 - 32
2 u = 122
1 u = 122 ÷ 2 = 61
Number of pages that Novel W has
= 1 u + 32
= 61 + 32
= 93
(b)
Number of pages that Novel X has
= 1 u + 32 + 20
= 93 + 20
= 113
Answer(s): (a) 93; (b) 113
