$984 more |
| Before |
1 u + $378 |
3 u |
| Change |
- $378 |
|
| After |
1 u |
3 u |
After
Amount that Mr Soh has = 1 u
Amount that Mr Neo has = 3 x 1 u = 3 u
Before
Amount that Mr Soh has = 1 u + 378
Amount that Mr Neo has = 3 u
Mr Neo had $984 more than Mr Soh at first.
If another $984 is given to Mr Soh at first, both will have the same amount at first.
3 u = 1 u + 378 + 984
3 u = 1 u + 1362
3 u - 1 u = 1362
2 u = 1362
1 u = 1362 ÷ 2 = 681
Amount that Mr Soh had at first
= 1 u + 378
= 681 + 378
= $1059
Answer(s): $1059
