Justin and George had some money at first. Justin received 2 times as much money as George every fortnight. At the end of 2 fortnights, both of them had the same amount of money. If George had $1320 at first and Justin had $2310 at the end of those 2 fortnights, what is the ratio of Justin's money to the total amount of money at first?

$2310 |
Amount that George received every fortnight
= 2310 - 1320
= $990
1 u = 990
Amount that Justin received every fortnight
= 2 u
= 2 x 990
= $1980
Amount that Justin had at first
= 2310 - 1980
= $330
Total amount that Justin and George had at first
= 1320 + 330
= $1650
Justin's amount : Total amount
330 : 1650
1 : 5
Answer(s): 1 : 5
