Magazine N has 69 fewer pages than Magazine P, and Magazine Q has 30 more pages than Magazine P. If Magazine N and Magazine P have a total of 127 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 + 69
Number of pages that Magazine Q has = 1 u + 69 + 30
Total number of pages that Magazine N and Magazine P have
= 1 u + 1 u + 69
= 2 u + 69
2 u + 69 = 127
2 u = 127 - 69
2 u = 58
1 u = 58 ÷ 2 = 29
Number of pages that Magazine P has
= 1 u + 69
= 29 + 69
= 98
(b)
Number of pages that Magazine Q has
= 1 u + 69 + 30
= 98 + 30
= 128
Answer(s): (a) 98; (b) 128
