Xandra had a textbook with 230 pages. She read 50% of the textbook on Thursday, 10% of the textbook 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% → 230
1% → 230 ÷ 100 = 2.3
Number of pages that Xandra read on Saturday in percent
= 100% - 50% - 10%
= 40%
Number of pages that Xandra read on Saturday
= 40 x 2.3
= 92
(b)
Number of more pages that Xandra read on Thursday than on Saturday in percent
= 50% - 40%
= 10%
10% → 10 x 2.3 = 23
Number of more pages that Xandra read on Thursday than on Saturday = 23
Answer(s): (a) 92; (b) 23
