Can't ping from PC1 to PC3 (Packet Tracer)

[Trinitrons]

I need help. I'm new and have been practicing Cisco routing on Cisco Packet Tracer and made a topology (Static) but it seems that I can't ping from PC1 to PC3, vice versa. I can ping PC1 to PC2 and PC3 to PC2 but when I ping from PC1 to PC3 or PC3 to PC1,  Request Timed Out shows. 

Here's the ip route I made from each router.
R1:

ip route 192.168.20.0 255.255.255.0 200.0.0.2

R2:

ip route 192.168.10.0 255.255.255.0 200.0.0.1

ip route 192.168.30.0 255.255.255.0 200.0.1.2

R3:

ip route 192.168.20.0 255.255.255.0 200.0.1.1

Attached is my .pkt topology.

Hi, this is probably not an issue anymore,

but I checked out your .pkt file. I did show ip route on R3 and did not find the 192.168.10.0 network in it. The issue seems to be that this command is not in R3

ip route 192.168.10.0 255.255.255.0 200.0.1.1

Please add that in R3 and try again, that worked for me.

Hopefully it helps
