Xuan and Ahmad had the same amount of savings at first. Then Xuan spent
14 of her savings and Ahmad spent
23 of his savings. If Xuan spent $665 less than Ahmad, how much did each of them have at first?
|
Xuan |
Ahmad |
Before |
4x3 = 12 u |
3x4 = 12 u |
Change |
1x3 = - 3 u |
2x4 = - 8 u |
After |
9 u |
4 u |
The amount that Xuan and Ahmad had at first is the same. Make the amount that Xuan and Ahmad each had the same. LCM of 4 and 3 is 12.
Amount that Xuan spent less than Ahmad
= 8 u - 3 u
= 5 u
5 u = 665
1 u = 665 ÷ 5 = 133
Amount that each of them had at first
= 12 u
= 12 x 133
= $1596
Answer(s): $1596
