Router 0 is connecting with a multilayer Switch

This network has 2 Vlans: Vlan 10 and Vlan 20

R0 has two subnets: g0/0.10: 192.168.10.1

g0/0.20: 192.168.20.1

How to make PC3 and PC4 ping each other and ping R0 successfully ?

I don't know how to configure the multilayer switch. Please write down the configuration.
