Japheth and Riordan had a total of 248 marbles at first. After Japheth bought 24 more marbles and Riordan gave away 16 marbles, Japheth now has the same number of marbles as Riordan. How many marbles did Japheth have at first?

Japheth |
Riordan |
Total |
| Before |
1 u - 24 |
1 u + 16 |
248 |
| Change |
+ 24 |
- 16 |
|
| After |
1 u |
1 u |
256 |
Total number of marbles in the end
= 248 + 24 - 16
= 256
2 u = 256
1 u = 256 ÷ 2 = 128
Number of marbles that Japheth had in the end
= 1 u
= 128
Number of marbles that Japheth had at first
= 128 - 24
= 104
Answer(s): 104
