Destination Host Unreachable issue in Packet Tracer

[tom.cass]

I'm a student at a college and I keep getting issues in doing the ping and it works when i ping the devices on the same side (for example yellow) but ı can't ping devices on the from different sides (for example yellow to pink). What is wrong with my setup?

Much appreciated

yellow area routes are not passed over to purple side for some reasons. Purple side does not know how to reach 192.168.30.0/24 192.168.40.0/24 as those are not in routing tables; hence failure in pinging. 

Try updating config so that all routers running RIP have same version 2 and no auto-summary (worked).  if that does not solve issue, then look and check HSRP.

Hello,

what instructions are you following ? Your HSRP setup does not make any sense:

HoGentAalst

interface GigabitEthernet0/1
ip address 192.168.10.254 255.255.255.0
duplex auto
speed auto
standby version 2
standby 1 ip 192.168.10.254
standby 1 priority 150
standby 1 preempt

LANROUTER1

interface GigabitEthernet0/0
ip address 192.168.20.254 255.255.255.0
ip helper-address 192.168.10.254
duplex auto
speed auto
standby version 2
standby 1 ip 192.168.20.254
standby 1 priority 150
standby 1 preempt

Both interfaces are neither on a common subnet, nor are they using the same standby IP address. The same is configured on the two routers on the right side. The standby IP address of the left and right top routers are identical to the actual IP addresses configured on the physical interfaces. There are also a lot of redundancies (unnecessary DHCP exclusions). I have cleaned up your network, attached the revised file (saved in Packet Tracer version 8.1, you will need to have this (latest) version installed in order to open the file).
