Penjelasan dengan langkah-langkah:

Uang Adi : uang Budi = 7 : 4. Uang Adi : uang Cindi = 2 : 3

selisih uang Cindi dan uang Budi = Rp52.000,-

uang Adi = a

uang budi = b

uang cindi = c

a : b = 7 : 4 = 14 : 8

a : c = 2 : 3 = 14 : 21

a : b : c = 14 : 8 : 21

misal total jumlah uang = x

a = 14/(14+8+21) × x

a = 14/43 x

b = 8/43 x

c = 21/43 x

c - b = 52000

21/43 x - 8/43 x = 52000

13/43 x = 52000

x = 52000/13 × 43

x = 4000 × 43

x = 172000

a + c =

14/43 x + 21/43 x =

35/43 x =

35/43 × 172000 =

35 × 4000 =

Rp 140000,-
