$704 more |
| Before |
1 u + $352 |
4 u |
| Change |
- $352 |
|
| After |
1 u |
4 u |
After
Amount that Mr Chen has = 1 u
Amount that Mr Ong has = 4 x 1 u = 4 u
Before
Amount that Mr Chen has = 1 u + 352
Amount that Mr Ong has = 4 u
Mr Ong had $704 more than Mr Chen at first.
If another $704 is given to Mr Chen at first, both will have the same amount at first.
4 u = 1 u + 352 + 704
4 u = 1 u + 1056
4 u - 1 u = 1056
3 u = 1056
1 u = 1056 ÷ 3 = 352
Amount that Mr Chen had at first
= 1 u + 352
= 352 + 352
= $704
Answer(s): $704
