Answer 1

dikt
uang rudi = 3/5 uang Sanusi
uang Sanusi = 3/4 uang Tarto.
Beda uang Rudy dan Tarto Rp 24.200,00

misal
uang Rudi = r ...(1)
uang tarto = r + Rp 24.200,00

uang Sanusi = 3/4 uang Tarto.
uang Sanusi
= 3/4 ( r + Rp 24.200,00)
= 3/4r + Rp 18,150,00 ....(2)


uang Rudi = 3/5 uang Sanusi
uang Sanusi = 3/4r + Rp 18,150,00 jadi
uang Rudi
= 3/5 (3/4r + Rp 18,150,00)
=9/20 r + Rp 10,890.00

uang Rudi = r... jadi
r = 9/20 r + Rp 10,890.00
11/20r = Rp 10,890.00
= 20/11 x Rp Rp 10,890.00
= Rp 19,800.00

Uang Rudi = Rp 19,800.00

Uang Sanusi = 5/3 x Rp 19,800.00 = Rp 33,000.00

Uang Tarto = 4/3 x Rp 33,000.00 = Rp 44,000.00

Answer 2

R : s = 3 : 5
s : t = 3 : 4
r : s : t = 9 : 15 : 20

R = 9/11 x 24200 = 9 x 2200 = 19800
S = 15/11 x 24200 = 15 x 2200 = 33000
T = 20/11 x 24200 = 20 x 2200 = 44000
