Roshel has 4 times as many wafers as Ivory. The total number of Roshel's and Ivory's wafers is 3 times of Marion's. Roshel and Ivory have 110 wafers more than Marion's. How many more wafers does Roshel have than Ivory?
| Roshel |
Ivory |
Marion |
| 4x3 |
1x3 |
|
| 3x5 |
1x5 |
| 12 u |
3 u |
5 u |
The total number of wafers that Roshel and Ivory have is repeated. Make the total number of wafers that Roshel and Ivory have the same. LCM of 5 and 3 is 15.
Total number of wafers that Roshel and Ivory have
= 12 u + 3 u
= 15 u
Number of more wafers that Roshel and Ivory have than Marion
= 15 u - 5 u
= 10 u
10 u = 110
1 u = 110 ÷ 10 = 11
Number of more wafers that Roshel has than Ivory
= 12 u - 3 u
= 9 u
= 9 x 11
= 99
Answer(s): 99
