Magazine X has 47 fewer pages than Magazine Y, and Magazine Z has 36 more pages than Magazine Y. If Magazine X and Magazine Y have a total of 141 pages,
- how many pages does Magazine Y have?
- how many pages does Magazine Z have?
(a)
Number of pages that Magazine X has = 1 u
Number of pages that Magazine Y has = 1 u + 47
Number of pages that Magazine Z has = 1 u + 47 + 36
Total number of pages that Magazine X and Magazine Y have
= 1 u + 1 u + 47
= 2 u + 47
2 u + 47 = 141
2 u = 141 - 47
2 u = 94
1 u = 94 ÷ 2 = 47
Number of pages that Magazine Y has
= 1 u + 47
= 47 + 47
= 94
(b)
Number of pages that Magazine Z has
= 1 u + 47 + 36
= 94 + 36
= 130
Answer(s): (a) 94; (b) 130
