$802 more |
| Before |
1 u + $424 |
3 u |
| Change |
- $424 |
|
| After |
1 u |
3 u |
After
Amount that Mr Chong has = 1 u
Amount that Mr Chiam has = 3 x 1 u = 3 u
Before
Amount that Mr Chong has = 1 u + 424
Amount that Mr Chiam has = 3 u
Mr Chiam had $802 more than Mr Chong at first.
If another $802 is given to Mr Chong at first, both will have the same amount at first.
3 u = 1 u + 424 + 802
3 u = 1 u + 1226
3 u - 1 u = 1226
2 u = 1226
1 u = 1226 ÷ 2 = 613
Amount that Mr Chong had at first
= 1 u + 424
= 613 + 424
= $1037
Answer(s): $1037
