$703 more |
| Before |
1 u + $392 |
4 u |
| Change |
- $392 |
|
| After |
1 u |
4 u |
After
Amount that Mr Ang has = 1 u
Amount that Mr Seow has = 4 x 1 u = 4 u
Before
Amount that Mr Ang has = 1 u + 392
Amount that Mr Seow has = 4 u
Mr Seow had $703 more than Mr Ang at first.
If another $703 is given to Mr Ang at first, both will have the same amount at first.
4 u = 1 u + 392 + 703
4 u = 1 u + 1095
4 u - 1 u = 1095
3 u = 1095
1 u = 1095 ÷ 3 = 365
Amount that Mr Ang had at first
= 1 u + 392
= 365 + 392
= $757
Answer(s): $757
