Fred and Henry had some money at first. Fred received 3 times as much money as Henry every month. At the end of 6 months, both of them had the same amount of money.

$1960 |
Amount that Henry received every month
= 1960 - 1330
= $630
1 u = 630
Amount that Fred received every month
= 3 u
= 3 x 630
= $1890
Amount that Fred had at first
= 1960 - 1890
= $70
Total amount that Fred and Henry had at first
= 1330 + 70
= $1400
Fred's amount : Total amount
70 : 1400
1 : 20
Answer(s): 1 : 20
