Tommy and Reggie had a total of 195 stamps at first. After Tommy bought 20 more stamps and Reggie gave away 11 stamps, Tommy now has the same number of stamps as Reggie. How many stamps did Tommy have at first?

Tommy |
Reggie |
Total |
| Before |
1 u - 20 |
1 u + 11 |
195 |
| Change |
+ 20 |
- 11 |
|
| After |
1 u |
1 u |
204 |
Total number of stamps in the end
= 195 + 20 - 11
= 204
2 u = 204
1 u = 204 ÷ 2 = 102
Number of stamps that Tommy had in the end
= 1 u
= 102
Number of stamps that Tommy had at first
= 102 - 20
= 82
Answer(s): 82
