Magazine N has 30 fewer pages than Magazine P, and Magazine Q has 19 more pages than Magazine P. If Magazine N and Magazine P have a total of 118 pages,
- how many pages does Magazine P have?
- how many pages does Magazine Q have?
(a)
Number of pages that Magazine N has = 1 u
Number of pages that Magazine P has = 1 u + 30
Number of pages that Magazine Q has = 1 u + 30 + 19
Total number of pages that Magazine N and Magazine P have
= 1 u + 1 u + 30
= 2 u + 30
2 u + 30 = 118
2 u = 118 - 30
2 u = 88
1 u = 88 ÷ 2 = 44
Number of pages that Magazine P has
= 1 u + 30
= 44 + 30
= 74
(b)
Number of pages that Magazine Q has
= 1 u + 30 + 19
= 74 + 19
= 93
Answer(s): (a) 74; (b) 93
