Yoko had a guide book with 330 pages. She read 50% of the guide book on Wednesday, 10% of the guide book on Thursday and the rest on Friday.
- How many pages did she read on Friday?
- How many more pages did she read on Wednesday than on Friday?
(a)
100% → 330
1% → 330 ÷ 100 = 3.3
Number of pages that Yoko read on Friday in percent
= 100% - 50% - 10%
= 40%
Number of pages that Yoko read on Friday
= 40 x 3.3
= 132
(b)
Number of more pages that Yoko read on Wednesday than on Friday in percent
= 50% - 40%
= 10%
10% → 10 x 3.3 = 33
Number of more pages that Yoko read on Wednesday than on Friday = 33
Answer(s): (a) 132; (b) 33
