Story book K has 58 fewer pages than Story book L, and Story book M has 17 more pages than Story book L. If Story book K and Story book L have a total of 200 pages,
- how many pages does Story book L have?
- how many pages does Story book M have?
(a)
Number of pages that Story book K has = 1 u
Number of pages that Story book L has = 1 u + 58
Number of pages that Story book M has = 1 u + 58 + 17
Total number of pages that Story book K and Story book L have
= 1 u + 1 u + 58
= 2 u + 58
2 u + 58 = 200
2 u = 200 - 58
2 u = 142
1 u = 142 ÷ 2 = 71
Number of pages that Story book L has
= 1 u + 58
= 71 + 58
= 129
(b)
Number of pages that Story book M has
= 1 u + 58 + 17
= 129 + 17
= 146
Answer(s): (a) 129; (b) 146
