Ken and Simon had $1632 altogether. After Ken spent
14 of his money and Simon spent
56 of his money, Ken was left with four times as much money as Simon. How much money did Simon have at first?

| Before |
4x4 =
16 u |
6x3 =
18 u |
$1632 |
| Change |
- 1x4 =
- 4 u |
- 5x3 =
- 15 u |
|
| After |
3x4 =
12 u |
1x3 =
3 u |
|
Comparing Ken
and Simon in the end |
4x3 =
12 u |
1x3 =
3 u |
|
The amount that Ken had in the end is repeated. Make the amount that Ken had in the end the same. LCM of 3 and 4 is 12.
Total amount that Ken and Simon had at first
= 16 u + 18 u
= 34 u
34 u = 1632
1 u = 1632 ÷ 34 = 48
Amount that Simon had at first
= 18 u
= 18 x 48
= $864
Answer(s): $864
