Andy and Japheth had some money at first. Andy received 4 times as much money as Japheth every day. At the end of 4 days, both of them had the same amount of money. If Japheth had $1470 at first and Andy had $1750 at the end of those 4 days, what is the ratio of Andy's money to the total amount of money at first?

$1750 |
$1750 |
Amount that Japheth received every day
= 1750 - 1470
= $280
1 u = 280
Amount that Andy received every day
= 4 u
= 4 x 280
= $1120
Amount that Andy had at first
= 1750 - 1120
= $630
Total amount that Andy and Japheth had at first
= 1470 + 630
= $2100
Andy's amount : Total amount
630 : 2100
3 : 10
Answer(s): 3 : 10
