A+b+c= 2403 q
c+ 246 q= a
b+ 78 q= a
b= a -78q
c= a -246q
a+a-78q+a-246q=2403
3a= 2403+78+246
a= 2727: 3
a= 909
b= 909-78=831q
c= 909- 246= 663q

1.I____I+246+78
2.I____I+246
3.I____I+78

Suma este 2403 .
2403-648=1755 ( suma partilor egale )
1755:3=585 ( o parte egala sau un segment )

585+78=663 q ( al treilea vagon )
585+246=831 q ( al doilea vagon )
585+246+78=909 q ( primul vagon )

Verificare :909+831+663=2403
