Some identical comics can be arranged in exactly 14 per row. If the same number of comics is arranged in rows of 9 comics each, there will be 3 more rows and 8 comics left over. How many comics are there altogether?

14 per row |
9 per row |
| Number |
1 u |
1 u + 3 |
| Value |
14 |
9 |
| Total value |
14 u |
9 u + 27 + 8 |
Number of rows if the comics are arranged in rows of 14 = 1 u
Number of rows if the comics are arranged in rows of 9 = 1 u + 3
Total number of comics if they are arranged in rows of 14
= 14 x 1 u
= 14 u
Total number of comics if they are arranged in rows of 9
= 9 x (1 u + 3) + 8
= 9 u + 27 + 8
= 9 u + 35
The total number of comics remains the same for both cases.
14 u = 9 u + 35
14 u - 9 u = 35
5 u = 35
1 u = 35 ÷ 5 = 7
Total number of comics
= 14 u
= 14 x 7
= 98
Answer(s): 98
