Andy and John had some money at first. Andy received 2 times as much money as John every day. At the end of 6 days, both of them had the same amount of money.

$2250 |
Amount that John received every day
= 2250 - 1260
= $990
1 u = 990
Amount that Andy received every day
= 2 u
= 2 x 990
= $1980
Amount that Andy had at first
= 2250 - 1980
= $270
Total amount that Andy and John had at first
= 1260 + 270
= $1530
Andy's amount : Total amount
270 : 1530
3 : 17
Answer(s): 3 : 17
