Story book G has 55 fewer pages than Story book H, and Story book J has 10 more pages than Story book H. If Story book G and Story book H have a total of 213 pages,
- how many pages does Story book H have?
- how many pages does Story book J have?
(a)
Number of pages that Story book G has = 1 u
Number of pages that Story book H has = 1 u + 55
Number of pages that Story book J has = 1 u + 55 + 10
Total number of pages that Story book G and Story book H have
= 1 u + 1 u + 55
= 2 u + 55
2 u + 55 = 213
2 u = 213 - 55
2 u = 158
1 u = 158 ÷ 2 = 79
Number of pages that Story book H has
= 1 u + 55
= 79 + 55
= 134
(b)
Number of pages that Story book J has
= 1 u + 55 + 10
= 134 + 10
= 144
Answer(s): (a) 134; (b) 144
