Eric and Pierre had some money at first. Eric received 2 times as much money as Pierre every week. At the end of 4 weeks, both of them had the same amount of money.

$2310 |
Amount that Pierre received every week
= 2310 - 1330
= $980
1 u = 980
Amount that Eric received every week
= 2 u
= 2 x 980
= $1960
Amount that Eric had at first
= 2310 - 1960
= $350
Total amount that Eric and Pierre had at first
= 1330 + 350
= $1680
Eric's amount : Total amount
350 : 1680
5 : 24
Answer(s): 5 : 24
