$920 more |
| Before |
1 u + $322 |
4 u |
| Change |
- $322 |
|
| After |
1 u |
4 u |
After
Amount that Mr Goh has = 1 u
Amount that Mr Peh has = 4 x 1 u = 4 u
Before
Amount that Mr Goh has = 1 u + 322
Amount that Mr Peh has = 4 u
Mr Peh had $920 more than Mr Goh at first.
If another $920 is given to Mr Goh at first, both will have the same amount at first.
4 u = 1 u + 322 + 920
4 u = 1 u + 1242
4 u - 1 u = 1242
3 u = 1242
1 u = 1242 ÷ 3 = 414
Amount that Mr Goh had at first
= 1 u + 322
= 414 + 322
= $736
Answer(s): $736
