Xuan had a novel with 280 pages. She read 50% of the novel on Monday, 35% of the novel on Tuesday and the rest on Wednesday.
- How many pages did she read on Wednesday?
- How many more pages did she read on Monday than on Wednesday?
(a)
100% → 280
1% → 280 ÷ 100 = 2.8
Number of pages that Xuan read on Wednesday in percent
= 100% - 50% - 35%
= 15%
Number of pages that Xuan read on Wednesday
= 15 x 2.8
= 42
(b)
Number of more pages that Xuan read on Monday than on Wednesday in percent
= 50% - 15%
= 35%
35% → 35 x 2.8 = 98
Number of more pages that Xuan read on Monday than on Wednesday = 98
Answer(s): (a) 42; (b) 98
