Lynn had a guide book with 180 pages. She read 40% of the guide book on Tuesday, 30% 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% → 180
1% → 180 ÷ 100 = 1.8
Number of pages that Lynn read on Thursday in percent
= 100% - 40% - 30%
= 30%
Number of pages that Lynn read on Thursday
= 30 x 1.8
= 54
(b)
Number of more pages that Lynn read on Tuesday than on Thursday in percent
= 40% - 30%
= 10%
10% → 10 x 1.8 = 18
Number of more pages that Lynn read on Tuesday than on Thursday = 18
Answer(s): (a) 54; (b) 18
