Pamela read
18 of the novel. If she had read another 306 pages, she would have read
56 of the whole novel altogether. How many pages were there in the novel?
|
Read |
Not read |
Total |
Before |
1x3 = 3 u |
7x3 = 21 u |
8x3 = 24 u |
Change |
+ 306 |
- 306 |
|
After |
5x4 = 20 u |
1x4 = 4 u |
6x4 = 24 u |
The total number of pages remains unchanged. Make the total number of pages the same. LCM of 8 and 6 is 24.
Number of additional pages that Pamela would have read
= 20 u - 3 u
= 17 u
17 u = 306
1 u = 306 ÷ 17 = 18
Number of pages in the novel
= 24 u
= 24 x 18
= 432
Answer(s): 432
