उत्तर : 1. "108"
व्याख्या :

There are two exceptions when a joint sitting cannot be summoned. They are for the following bills:

Constitution Amendment Bill: According to Article 368, the Constitution can be amended only by a 2/3rd majority in both Houses. There is no provision for a joint sitting in case of a disagreement between both Houses.

Money Bill (Article 110): As per the Constitution, money bills require the Lok Sabha’s approval only. 

Even if the Rajya Sabha does not pass the money bill within 14 days, the bill is considered passed by both Houses after 14 days is over.

The Rajya Sabha can make recommendations to the Bill which the Lok Sabha is not required to accept.

Thus, in the case of a money bill, the necessity of a joint sitting does not arise.
