Magazine Q has 24 fewer pages than Magazine R, and Magazine S has 24 more pages than Magazine R. If Magazine Q and Magazine R have a total of 100 pages,
- how many pages does Magazine R have?
- how many pages does Magazine S have?
(a)
Number of pages that Magazine Q has = 1 u
Number of pages that Magazine R has = 1 u + 24
Number of pages that Magazine S has = 1 u + 24 + 24
Total number of pages that Magazine Q and Magazine R have
= 1 u + 1 u + 24
= 2 u + 24
2 u + 24 = 100
2 u = 100 - 24
2 u = 76
1 u = 76 ÷ 2 = 38
Number of pages that Magazine R has
= 1 u + 24
= 38 + 24
= 62
(b)
Number of pages that Magazine S has
= 1 u + 24 + 24
= 62 + 24
= 86
Answer(s): (a) 62; (b) 86
