Hi Ankit,
You can achieve it in this way
Create one catalog(ex:catalog_x) with three tiles.
Create three groups
1.Group_x(add 1st tile to this group)
2.Group_y (add 2nd tile to this group)
3.Group_z (add both tiles to this group)
Then Create 3 roles.
1. Role_1(assign catalog_X and group_x)
2. Role_2(assign catalog_X and group_y)
3. Role_3(assign catalog_X and group_z)
Assign the above roles to the users as per your requirement.

Viswa
