Marion had a novel with 120 pages. She read 50% of the novel on Tuesday, 20% of the novel 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% → 120
1% → 120 ÷ 100 = 1.2
Number of pages that Marion read on Thursday in percent
= 100% - 50% - 20%
= 30%
Number of pages that Marion read on Thursday
= 30 x 1.2
= 36
(b)
Number of more pages that Marion read on Tuesday than on Thursday in percent
= 50% - 30%
= 20%
20% → 20 x 1.2 = 24
Number of more pages that Marion read on Tuesday than on Thursday = 24
Answer(s): (a) 36; (b) 24
