Magazine J has 54 fewer pages than Magazine K, and Magazine L has 28 more pages than Magazine K. If Magazine J and Magazine K have a total of 188 pages,
- how many pages does Magazine K have?
- how many pages does Magazine L have?
(a)
Number of pages that Magazine J has = 1 u
Number of pages that Magazine K has = 1 u + 54
Number of pages that Magazine L has = 1 u + 54 + 28
Total number of pages that Magazine J and Magazine K have
= 1 u + 1 u + 54
= 2 u + 54
2 u + 54 = 188
2 u = 188 - 54
2 u = 134
1 u = 134 ÷ 2 = 67
Number of pages that Magazine K has
= 1 u + 54
= 67 + 54
= 121
(b)
Number of pages that Magazine L has
= 1 u + 54 + 28
= 121 + 28
= 149
Answer(s): (a) 121; (b) 149
