Savings

Paul has a by half greater savings than half Stanley, but the same savings as Radek. Staney save 120 CZK less than Radek. What savings have 3 boys together?

Correct answer:

x =  960 Kc

Step-by-step explanation:


p=s+s/2
p=r
s = r-120
x=p+s+r

2p-3s = 0
p-r = 0
r-s = 120
p+r+s-x = 0

p = 360
r = 360
s = 240
x = 960
