I zi : /________/
a II-a zi: /________/ + 25
a II-a zi: /________/ + 25 + 25 total 1050 mere
a IV-a zi: /________/ + 25 + 25 + 25
1050 - ( 25 x 6) = 1050 - 150 = 900
900 : 4 = 225 (un segment)
I zi = 225 mere
a II-a zi = 225 + 25 = 250 mere
a III-a zi = 225 + 50 = 275 mere
a IV-a zi= 225 + 75 = 300 mere
Total: 225 + 250 + 275 + 300 = 475 + 575 = 1050 mere
