In Jainism, the number of Āgams depends on the tradition:

• Śvetāmbara Jain tradition: usually says there are 45 Āgams
• Digambara Jain tradition: does not accept the Śvetāmbara Āgams as original canon; instead, it recognizes the lost original scriptures and later texts such as Ṣaṭkhaṇḍāgama and Kaṣāyapāhuḍa as highly important

So, if someone asks generally, the most common answer is:

Śvetāmbara: 45 Āgams

If you want, I can also give the names of the 45 Āgams.
