Answer 1

a)--------
b)--------...+2
c)--------....+2...+2
D)--------.....+2....+2...+2 In total 900.
 Egalam:  900 - 12=   888
Nr mic (a) 888:4=222
Nr b:222+2=224
Nr c:222+4=226
Nr d:222+6=228

Answer 2

a |-----|
b |-----|2|
c |-----|2|2|
d |-----|2|2|2|     } 900.

900 - ( 2+2+2+2+2+2) = 900 - 12 = 888   ( 4 segmente egale)
888 : 4 = 222 (a)
222 + 2 = 224 (b)
222 +2+2 = 226 (c)
222+2+2+2 = 228 (d)
Verificare: 222 + 224 + 226 + 228 = 900 .( a+b+c+d).
