Question

Perbandingan jumlah tabungan A dan B adalah 3 : 4 , sedangkan jumlah tabungan A sama dg 2/3 Dr tabungan C. Jika jml tabungan A , B, dan C Rp4.600.00 , maka selisih tabungan A dan B adl

Answer 1

=
Sehingga di dapat B = 4/3 A
A = 2/3 C
A+ B + C = 4.600
Maka (2/3 C) + ( 4/3 x 2/3) C + C = 2/3 + 8/9 + 1 = 4.600
= 14/9 + 9/9 = 23/9 C = 4.600
Sehingga di dapat C= 1.800
Maka, A = 2/3 x 1.800 = 1.200
Dan B, 4/3 x 1.200 = 1.600
Selisih A dan B = 1.600 - 1.200 = 400

Answer 2

A = 3/7 = 6/14 = 6
B = 4/7 = 8/14 = 8
C = 3/2 A = 3/2 × 3/7 = 9/14 = 9

A:B:C = 6:8:9
A = 6/23 × 4600 = 1200
B = 8/23 × 4600 = 1600
C = 9/23 × 4600 = 1800

Selisih A dan B = 1600-1200 = 400
