Tim and Riordan had some money at first. Tim received 2 times as much money as Riordan every fortnight. At the end of 4 fortnights, both of them had the same amount of money. If Riordan had $1140 at first and Tim had $1860 at the end of those 4 fortnights, what is the ratio of Tim's money to the total amount of money at first?

$1860 |
Amount that Riordan received every fortnight
= 1860 - 1140
= $720
1 u = 720
Amount that Tim received every fortnight
= 2 u
= 2 x 720
= $1440
Amount that Tim had at first
= 1860 - 1440
= $420
Total amount that Tim and Riordan had at first
= 1140 + 420
= $1560
Tim's amount : Total amount
420 : 1560
7 : 26
Answer(s): 7 : 26
