Riordan and Neave had some money at first. Riordan received 4 times as much money as Neave every week. At the end of 4 weeks, both of them had the same amount of money. If Neave had $1350 at first and Riordan had $1710 at the end of those 4 weeks, what is the ratio of Riordan's money to the total amount of money at first?

$1710 |
Amount that Neave received every week
= 1710 - 1350
= $360
1 u = 360
Amount that Riordan received every week
= 4 u
= 4 x 360
= $1440
Amount that Riordan had at first
= 1710 - 1440
= $270
Total amount that Riordan and Neave had at first
= 1350 + 270
= $1620
Riordan's amount : Total amount
270 : 1620
1 : 6
Answer(s): 1 : 6
