Verified answer
Siti = 3xwati = 5x
ani = 7x
ani - siti
= 7x - 3x = 100 000
4x = 100 000
x = 100 000/4
= 25 000
ani+wati+siti
= 3x + 5x + 7x
= 15x
= 15 x 25 000
= 375 000
selisih perbandingan ani dan siti= 7-4=3
selisih tabungan ani dan siti= Rp 100.000
jawab:
jumlah tabungan ketiganya= 15/3 ×100.000
=500.000
