Which level is this question for - P5 or P6?
Before
A : B
125 : 100
5u : 4u
20u : 12u

Change
A spent $50 and B spent $16
A : B
-50 : -16
-200 : -48

After
A : B
3p : 4p
12p : 12p

20u-200=12u-48
8u=152
u=19

A (at first): 5u = 5x19=95
Amount of money that A has at first = $95

Check
A : B
5u : 4u
95 : 76

Spent
A : B
50 : 16

After
45 : 60
3: 4

Edited to include the Strategy
