Story book E has 40 fewer pages than Story book F, and Story book G has 36 more pages than Story book F. If Story book E and Story book F have a total of 134 pages,
- how many pages does Story book F have?
- how many pages does Story book G have?
(a)
Number of pages that Story book E has = 1 u
Number of pages that Story book F has = 1 u + 40
Number of pages that Story book G has = 1 u + 40 + 36
Total number of pages that Story book E and Story book F have
= 1 u + 1 u + 40
= 2 u + 40
2 u + 40 = 134
2 u = 134 - 40
2 u = 94
1 u = 94 ÷ 2 = 47
Number of pages that Story book F has
= 1 u + 40
= 47 + 40
= 87
(b)
Number of pages that Story book G has
= 1 u + 40 + 36
= 87 + 36
= 123
Answer(s): (a) 87; (b) 123
