Vaidev and Ben had some money at first. Vaidev received 2 times as much money as Ben every fortnight. At the end of 8 fortnights, both of them had the same amount of money. If Ben had $1200 at first and Vaidev had $1680 at the end of those 8 fortnights, what is the ratio of Vaidev's money to the total amount of money at first?

$1680 |
Amount that Ben received every fortnight
= 1680 - 1200
= $480
1 u = 480
Amount that Vaidev received every fortnight
= 2 u
= 2 x 480
= $960
Amount that Vaidev had at first
= 1680 - 960
= $720
Total amount that Vaidev and Ben had at first
= 1200 + 720
= $1920
Vaidev's amount : Total amount
720 : 1920
3 : 8
Answer(s): 3 : 8
