$721 more |
| Before |
1 u + $386 |
4 u |
| Change |
- $386 |
|
| After |
1 u |
4 u |
After
Amount that Mr Leow has = 1 u
Amount that Mr Seah has = 4 x 1 u = 4 u
Before
Amount that Mr Leow has = 1 u + 386
Amount that Mr Seah has = 4 u
Mr Seah had $721 more than Mr Leow at first.
If another $721 is given to Mr Leow at first, both will have the same amount at first.
4 u = 1 u + 386 + 721
4 u = 1 u + 1107
4 u - 1 u = 1107
3 u = 1107
1 u = 1107 ÷ 3 = 369
Amount that Mr Leow had at first
= 1 u + 386
= 369 + 386
= $755
Answer(s): $755
