Ahmad and Ivan had some money at first. Ahmad received 3 times as much money as Ivan every week. At the end of 4 weeks, both of them had the same amount of money. If Ivan had $1400 at first and Ahmad had $1700 at the end of those 4 weeks, what is the ratio of Ahmad's money to the total amount of money at first?

$1700 |
$1700 |
Amount that Ivan received every week
= 1700 - 1400
= $300
1 u = 300
Amount that Ahmad received every week
= 3 u
= 3 x 300
= $900
Amount that Ahmad had at first
= 1700 - 900
= $800
Total amount that Ahmad and Ivan had at first
= 1400 + 800
= $2200
Ahmad's amount : Total amount
800 : 2200
4 : 11
Answer(s): 4 : 11
