16 muncitori................y zile
x=(12*8)/4=96/4=24 zile
y=(12*8)/16=96/16=6 zile
8 muncitori ----------12 zile
4 muncitori -----------x zile
x = 8 × 12 : 4
x = 96 : 4
x = 24 zile
8 muncitori ----------12 zile
16 muncitori ---------x zile
x = 8 × 12 : 16
x = 96 : 16
x = 6 zile
4 muncitori -----------x zile
x = 8 × 12 : 4
x = 96 : 4
x = 24 zile
