Notez cu s suma de bani.
 \frac{1}{4} * s =  \frac{s}{4}
rest: s -  \frac{s}{4} =  \frac{3*s}{4}
cheltuie apoi  \frac{1}{6} *  \frac{3s}{4} =  \frac{s}{8}
noul rest : s -  \frac{s}{4} -  \frac{s}{8} =  \frac{5s}{8}  \frac{1}{3} *  \frac{5s}{8} =  \frac{5s}{24}

s-  \frac{s}{4} -  \frac{s}{8} - \frac{5s}{24} - 120 = 600

 \frac{24s-6s-3s-5s-120*24}{24} =600
10s -120 * 24 = 600 *24
s = 1728

Verificare : 1728 : 4 = 432
rest: 1728 - 432 = 1296
1296 : 6 = 216
noul rest : 1728-432-216 = 1080
1080 : 3 = 360
Se mai cheltuie 120 
1728 - 432 - 216 - 360 - 120 =600
