$946 more |
| Before |
1 u + $341 |
4 u |
| Change |
- $341 |
|
| After |
1 u |
4 u |
After
Amount that Mr Yap has = 1 u
Amount that Mr Seah has = 4 x 1 u = 4 u
Before
Amount that Mr Yap has = 1 u + 341
Amount that Mr Seah has = 4 u
Mr Seah had $946 more than Mr Yap at first.
If another $946 is given to Mr Yap at first, both will have the same amount at first.
4 u = 1 u + 341 + 946
4 u = 1 u + 1287
4 u - 1 u = 1287
3 u = 1287
1 u = 1287 ÷ 3 = 429
Amount that Mr Yap had at first
= 1 u + 341
= 429 + 341
= $770
Answer(s): $770
