Răspuns: 56 alune
Explicație pas cu pas:
12 = 8 + 4; 15 = 11 + 4 => impartitorul > rest cu 4
_________________________________________
n + 4 = 12 x ( c + 1 ) = 15 x ( c + 1 )
n + 4 = c.m.m.m,c al numerelor 12 si 15
12 = 4 x 3
15 = 3 x 5
__________
n + 4 = 4 x 3 x 5
n + 4 = 60
n = 60 - 4
n = 56 alune sunt in punga

Verific:
56 : 12 = 4 rest 8
56 : 15 = 3 rest 11
