Ahmad and Seth had some money at first. Ahmad received 2 times as much money as Seth every day. At the end of 2 days, both of them had the same amount of money. If Seth had $1000 at first and Ahmad had $1600 at the end of those 2 days, what is the ratio of Ahmad's money to the total amount of money at first?

$1600 |
Amount that Seth received every day
= 1600 - 1000
= $600
1 u = 600
Amount that Ahmad received every day
= 2 u
= 2 x 600
= $1200
Amount that Ahmad had at first
= 1600 - 1200
= $400
Total amount that Ahmad and Seth had at first
= 1000 + 400
= $1400
Ahmad's amount : Total amount
400 : 1400
2 : 7
Answer(s): 2 : 7
