A/B = 3/5
5A = 3B
10A = 6B  ................................(1)

B/C= 4/6
6B = 4C ...................................(2)

DARI PERSAMAAN 1 DAN 2 DIDAPAT
10A = 4C ..................................3)

A + C = 224ooo
A= 224000 - C  substitusikan ke pers (3) didapat
10 x (224000 - C) = 4C
2240000 - 10C = 4C
14C = 2240000
C = 2240000/14 = 160000 substitusikan ke pers 2 didapat
6B = 4 x 160000 = 640000
  B = 640000/6 = 106666,67
maka jumlah uan B = Rp.106.666,67
