Guide book H has 78 fewer pages than Guide book J, and Guide book K has 27 more pages than Guide book J. If Guide book H and Guide book J have a total of 244 pages,
- how many pages does Guide book J have?
- how many pages does Guide book K have?
(a)
Number of pages that Guide book H has = 1 u
Number of pages that Guide book J has = 1 u + 78
Number of pages that Guide book K has = 1 u + 78 + 27
Total number of pages that Guide book H and Guide book J have
= 1 u + 1 u + 78
= 2 u + 78
2 u + 78 = 244
2 u = 244 - 78
2 u = 166
1 u = 166 ÷ 2 = 83
Number of pages that Guide book J has
= 1 u + 78
= 83 + 78
= 161
(b)
Number of pages that Guide book K has
= 1 u + 78 + 27
= 161 + 27
= 188
Answer(s): (a) 161; (b) 188
