Two routers are configured with RIPv1 and RIPv2 respectively. Will both communicate or only one can understand ?

you should set the router that runs V2 to send and recive V1 Updates
using the below interface commands
ip rip receive version 1
ip rip send version 1

But what about ripv1 router?
Is it automatically takes the update or we have to set some commandes?

Yes they will communicate, but Only Rip version 1 is going to be sent and accepted by Ripv1 Router.
Enabling Version2 rip , would allow a router to send and recieve version 1/2 updates , while enabling Ripv1 only allows a router to send and recieve version1 updates.

Hello Kaustubh,
with default settings
RIPV2 router will understand the other router updates, but it will ignore them because it expects to receive RIPv2 messages as specified in version command.
see
The following example configures the interface to receive both RIP Version 1 and Version 2 packets:
ip rip receive version 1 2

RIPV1 only router cannot understand RIPv2 messages and will discard them.
So they shouldn't exchange routing information without additional commands.
Hope to help
