Yen had a non-fiction book with 270 pages. She read 50% of the non-fiction book on Thursday, 35% of the non-fiction book on Friday and the rest on Saturday.
- How many pages did she read on Saturday?
- How many more pages did she read on Thursday than on Saturday?
(a)
100% → 270
1% → 270 ÷ 100 = 2.7
Number of pages that Yen read on Saturday in percent
= 100% - 50% - 35%
= 15%
Number of pages that Yen read on Saturday
= 15 x 2.7
= 40.5
(b)
Number of more pages that Yen read on Thursday than on Saturday in percent
= 50% - 15%
= 35%
35% → 35 x 2.7 = 94.5
Number of more pages that Yen read on Thursday than on Saturday = 94.5
Answer(s): (a) 40.5; (b) 94.5
