Asher had
38 the number of stamps that Luis had at first. After Luis gave Asher 136 of his stamps, Asher had
45 the number of stamps that Luis had. How many stamps did Luis have in the end?

Luis |
Total |
Before |
3x9 = 27 u |
8x9 = 72 u |
11x9 = 99 u |
Change |
+ 17 u |
- 17 u |
|
After |
4x11 = 44 u |
5x11 = 55 u |
9x11 = 99 u |
The total number of stamps that Asher and Luis had at first and in the end remains unchanged. Make the total number of stamps the same. LCM of 11 and 9 is 99.
Number of stamps that Luis gave Asher
= 44 u - 27 u
= 17 u
17 u = 136
1 u = 136 ÷ 17 = 8
Number of stamps that Luis had in the end
= 55 u
= 55 x 8
= 440
Answer(s): 440
