Bunga A = 5/100 A bunga B = 6/100 B A + B = 250.000 A = 250.000 - B
bunga B = 6200 + bunga A 6/100 B = 6200 + 5/100 A 6/100 B = 6200 + 5/100 (250.000 - B) 6/100 B = 6200 + 12500 - 5/100 B 6/100 B = 18700 - 5/100 B = 18700 11/100 B = 18700 B = 18700 × 100/11 B = 170.000
besar uang yg ditabung dibank A = 250.000 - 170.000 = Rp 80.000 (A)
bunga B = 6/100 B
A + B = 250.000
A = 250.000 - B
bunga B = 6200 + bunga A
6/100 B = 6200 + 5/100 A
6/100 B = 6200 + 5/100 (250.000 - B)
6/100 B = 6200 + 12500 - 5/100 B
6/100 B = 18700 - 5/100 B
= 18700
11/100 B = 18700
B = 18700 × 100/11
B = 170.000
besar uang yg ditabung dibank A = 250.000 - 170.000
= Rp 80.000 (A)
