Oliver had
38 the number of stamps that Glen had at first. After Glen gave Oliver 108 of his stamps, Oliver had
35 the number of stamps that Glen had. How many stamps did Oliver have at first?

Oliver |
Glen |
Total |
Before |
3x8 = 24 u |
8x8 = 64 u |
11x8 = 88 u |
Change |
+ 9 u |
- 9 u |
|
After |
3x11 = 33 u |
5x11 = 55 u |
8x11 = 88 u |
The total number of stamps that Oliver and Glen had at first and in the end remains unchanged. Make the total number of stamps the same. LCM of 11 and 8 is 88.
Number of stamps that Glen gave Oliver
= 33 u - 24 u
= 9 u
9 u = 108
1 u = 108 ÷ 9 = 12
Number of stamps that Oliver had at first
= 24 u
= 24 x 12
= 288
Answer(s): 288
