Xavier had
58 the number of stamps that Nick had at first. After Nick gave Xavier 24 of his stamps, Xavier had
34 the number of stamps that Nick had. How many stamps did Xavier have at first?
|
Xavier |
Nick |
Total |
Before |
5x7 = 35 u |
8x7 = 56 u |
13x7 = 91 u |
Change |
+ 4 u |
- 4 u |
|
After |
3x13 = 39 u |
4x13 = 52 u |
7x13 = 91 u |
The total number of stamps that Xavier and Nick had at first and in the end remains unchanged. Make the total number of stamps the same. LCM of 13 and 7 is 91.
Number of stamps that Nick gave Xavier
= 39 u - 35 u
= 4 u
4 u = 24
1 u = 24 ÷ 4 = 6
Number of stamps that Xavier had at first
= 35 u
= 35 x 6
= 210
Answer(s): 210
