Total amount that Pamela and Fanny had at first
= 5 u + 5 u + 60
= 10 u + 60
10 u + 60 = 390
5 u + 4 u = 390 - 60
10 u = 330
1 u = 330 ÷ 10 = 33
Amount that Pamela had at first
= 5 u
= 5 x 33
= $165
Amount that Fanny had at first
= 390 - 165
= $225
At first
Pamela : Fanny
165 : 225
11 : 15
Answer(s): 11 : 15
