Colouring book F has 28 fewer pages than Colouring book G, and Colouring book H has 18 more pages than Colouring book G. If Colouring book F and Colouring book G have a total of 242 pages,

1. how many pages does Colouring book G have?
2. how many pages does Colouring book H have?

(a)
Number of pages that Colouring book F has = 1 u
Number of pages that Colouring book G has = 1 u + 28
Number of pages that Colouring book H has = 1 u + 28 + 18

Total number of pages that Colouring book F and Colouring book G have
= 1 u + 1 u + 28
= 2 u + 28

2 u + 28 = 242
2 u = 242 - 28
2 u = 214

1 u = 214 ÷ 2 = 107

Number of pages that  Colouring book G has
= 1 u + 28
= 107 + 28
= 135

(b)
Number of pages that Colouring book H has
= 1 u + 28 + 18
= 135 + 18
= 153

Answer(s): (a) 135; (b) 153
