Hilda read
27 of the manuscript. If she had read another 190 pages, she would have read
58 of the whole manuscript altogether. How many pages were there in the manuscript?

Total |
| Before |
2x8 =
16 u |
5x8 =
40 u |
7x8 =
56 u |
| Change |
+ 190 |
- 190 |
|
| After |
5x7 =
35 u |
3x7 =
21 u |
8x7 =
56 u |
The total number of pages remains unchanged. Make the total number of pages the same. LCM of 7 and 8 is 56.
Number of additional pages that Hilda would have read
= 35 u - 16 u
= 19 u
19 u = 190
1 u = 190 ÷ 19 = 10
Number of pages in the manuscript
= 56 u
= 56 x 10
= 560
Answer(s): 560
