Shiyun and Roshel had the same number of coins. After Shiyun had given away 64 coins, Roshel had 5 times as many coins as Shiyun. How many coins did each of them have at first?
| |
Shiyun |
Roshel |
| Before |
1 u + 64 |
5 u |
| Change |
- 64 |
|
| After |
1 u |
5 u |
Number of coins that Roshel had remains unchanged.
Number of coins that Shiyun and Roshel had at first is equal.
5 u = 1 u + 64
5 u - 1 u = 64
4 u = 64
1 u = 64 ÷ 4= 16
Number of coins that each of them had at first
= 1 u + 64
= 16 + 64
= 80
Answer(s): 80
