Răspuns :
prima zi = 40 × 300 : 100 = 120
300 - 120 = 180 ramase
a doua zi = 4 / 5 × 180 = 144
a treia zi = 180 - 144 = 36
Verificare : 120 + 144 + 36 = 300 piese
300 - 120 = 180 ramase
a doua zi = 4 / 5 × 180 = 144
a treia zi = 180 - 144 = 36
Verificare : 120 + 144 + 36 = 300 piese
1 zi : 40 • 300 / 100 = 120
300 - 120 = 180 piese ramase
2 zi : 4 / 5 • 180 = 144
3 zi : 180 - 144 = 36
verificare : 120 + 144 + 36 = 300 ✔
