Answer 1

a |----------|
b |----------|1|
c |----------|1|1|
d |----------|1|1|1|
e |----------|1|1|1|1|        } 615.

615 - ( 1+1+1+1+1+1+1+1+1+1)= 615 - 10 = 605 ( 5 segmente egale cu a)
605 : 5 = 121 (a)
121+1=122 (b)
121 +1+1 = 123 (c)
121 +1 + 1+1=124 (d)
121 +1 +1 +1 +1 = 125 (e)
Verificam : 121 +122 +123 +124 +125=615. ( a+b+c+d+e).
