| Before |
1 u + $468 |
5 u |
| Change |
- $468 |
|
| After |
1 u |
5 u |
After
Amount that Mr Sim has = 1 u
Amount that Mr Sher has = 5 x 1 u = 5 u
Before
Amount that Mr Sim has = 1 u + 468
Amount that Mr Sher has = 5 u
Mr Sher had $748 more than Mr Sim at first.
If another $748 is given to Mr Sim at first, both will have the same amount at first.
5 u = 1 u + 468 + 748
5 u = 1 u + 1216
5 u - 1 u = 1216
4 u = 1216
1 u = 1216 ÷ 4 = 304
Amount that Mr Sim had at first
= 1 u + 468
= 304 + 468
= $772
Answer(s): $772
