Albert and David had some money at first. Albert received 2 times as much money as David every week. At the end of 8 weeks, both of them had the same amount of money.

$2300 |
Amount that David received every week
= 2300 - 1380
= $920
1 u = 920
Amount that Albert received every week
= 2 u
= 2 x 920
= $1840
Amount that Albert had at first
= 2300 - 1840
= $460
Total amount that Albert and David had at first
= 1380 + 460
= $1840
Albert's amount : Total amount
460 : 1840
1 : 4
Answer(s): 1 : 4
