Last month, Shiyun had thrice as much savings as Ian. This month, Ian saves $300. As a result, he now has twice as much savings as Shiyun. What is their total savings now?

Total |
| Before |
3 u |
1 u |

| Change |
|
+ $300 |
|
| After |
1x3 =
3 u |
2x3 =
6 u |
9 u |
The amount of savings that Shiyun has at first and in the end remains unchanged. Make the amount of savings that Shiyun has the same. LCM of 3 and 1 is 3.
Amount that Ian saved
= 6 u - 1 u
= 5 u
5 u = 300
1 u = 300 ÷ 5 = 60
Total savings now
= 3 u + 6 u
= 9 u
= 9 x 60
= $540
Answer(s): $540
