Henry and Mark had some money at first. Henry received 2 times as much money as Mark every week. At the end of 4 weeks, both of them had the same amount of money. If Mark had $1020 at first and Henry had $1920 at the end of those 4 weeks, what is the ratio of Henry's money to the total amount of money at first?

$1920 |
Amount that Mark received every week
= 1920 - 1020
= $900
1 u = 900
Amount that Henry received every week
= 2 u
= 2 x 900
= $1800
Amount that Henry had at first
= 1920 - 1800
= $120
Total amount that Henry and Mark had at first
= 1020 + 120
= $1140
Henry's amount : Total amount
120 : 1140
2 : 19
Answer(s): 2 : 19
