David and Liam had some money at first. David received 4 times as much money as Liam every fortnight. At the end of 2 fortnights, both of them had the same amount of money. If Liam had $1400 at first and David had $1750 at the end of those 2 fortnights, what is the ratio of David's money to the total amount of money at first?

$1750 |
Amount that Liam received every fortnight
= 1750 - 1400
= $350
1 u = 350
Amount that David received every fortnight
= 4 u
= 4 x 350
= $1400
Amount that David had at first
= 1750 - 1400
= $350
Total amount that David and Liam had at first
= 1400 + 350
= $1750
David's amount : Total amount
350 : 1750
1 : 5
Answer(s): 1 : 5
