Answer:

We would have started the dinner if she had been there.

• The above sentence is an example of type-3 ''if conditional clause''.  

• In type-3 ''if conditional clause'', we use ''would + have + participle'' in the main clause and ''past perfect'' in the ''if clause''.

We would have started the dinner if she had been there.

• I would have passed the test = main clause

• if I had studied. = if clause
