Zoe had a guide book with 150 pages. She read 40% of the guide book on Tuesday, 25% of the guide book on Wednesday and the rest on Thursday.
- How many pages did she read on Thursday?
- How many more pages did she read on Tuesday than on Thursday?
(a)
100% → 150
1% → 150 ÷ 100 = 1.5
Number of pages that Zoe read on Thursday in percent
= 100% - 40% - 25%
= 35%
Number of pages that Zoe read on Thursday
= 35 x 1.5
= 52.5
(b)
Number of more pages that Zoe read on Tuesday than on Thursday in percent
= 40% - 35%
= 5%
5% → 5 x 1.5 = 7.5
Number of more pages that Zoe read on Tuesday than on Thursday = 7.5
Answer(s): (a) 52.5; (b) 7.5
