| Change |
- $399 |
|
| After |
1 u |
5 u |
After
Amount that Mr Ang has = 1 u
Amount that Mr Yong has = 5 x 1 u = 5 u
Before
Amount that Mr Ang has = 1 u + 399
Amount that Mr Yong has = 5 u
Mr Yong had $709 more than Mr Ang at first.
If another $709 is given to Mr Ang at first, both will have the same amount at first.
5 u = 1 u + 399 + 709
5 u = 1 u + 1108
5 u - 1 u = 1108
4 u = 1108
1 u = 1108 ÷ 4 = 277
Amount that Mr Ang had at first
= 1 u + 399
= 277 + 399
= $676
Answer(s): $676
