| Change |
- $482 |
|
| After |
1 u |
3 u |
After
Amount that Mr Loh has = 1 u
Amount that Mr Kong has = 3 x 1 u = 3 u
Before
Amount that Mr Loh has = 1 u + 482
Amount that Mr Kong has = 3 u
Mr Kong had $712 more than Mr Loh at first.
If another $712 is given to Mr Loh at first, both will have the same amount at first.
3 u = 1 u + 482 + 712
3 u = 1 u + 1194
3 u - 1 u = 1194
2 u = 1194
1 u = 1194 ÷ 2 = 597
Amount that Mr Loh had at first
= 1 u + 482
= 597 + 482
= $1079
Answer(s): $1079
