Story book E has 62 fewer pages than Story book F, and Story book G has 27 more pages than Story book F. If Story book E and Story book F have a total of 242 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 + 62
Number of pages that Story book G has = 1 u + 62 + 27
Total number of pages that Story book E and Story book F have
= 1 u + 1 u + 62
= 2 u + 62
2 u + 62 = 242
2 u = 242 - 62
2 u = 180
1 u = 180 ÷ 2 = 90
Number of pages that Story book F has
= 1 u + 62
= 90 + 62
= 152
(b)
Number of pages that Story book G has
= 1 u + 62 + 27
= 152 + 27
= 179
Answer(s): (a) 152; (b) 179
