Story book G has 37 fewer pages than Story book H, and Story book J has 35 more pages than Story book H. If Story book G and Story book H have a total of 243 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 + 37
Number of pages that Story book J has = 1 u + 37 + 35
Total number of pages that Story book G and Story book H have
= 1 u + 1 u + 37
= 2 u + 37
2 u + 37 = 243
2 u = 243 - 37
2 u = 206
1 u = 206 ÷ 2 = 103
Number of pages that Story book H has
= 1 u + 37
= 103 + 37
= 140
(b)
Number of pages that Story book J has
= 1 u + 37 + 35
= 140 + 35
= 175
Answer(s): (a) 140; (b) 175
