| Change |
- $495 |
|
| After |
1 u |
4 u |
After
Amount that Mr Hun has = 1 u
Amount that Mr Seah has = 4 x 1 u = 4 u
Before
Amount that Mr Hun has = 1 u + 495
Amount that Mr Seah has = 4 u
Mr Seah had $675 more than Mr Hun at first.
If another $675 is given to Mr Hun at first, both will have the same amount at first.
4 u = 1 u + 495 + 675
4 u = 1 u + 1170
4 u - 1 u = 1170
3 u = 1170
1 u = 1170 ÷ 3 = 390
Amount that Mr Hun had at first
= 1 u + 495
= 390 + 495
= $885
Answer(s): $885
