Final answer:
The question lacks context to determine how many RAC there are in 5 nocs, as the acronyms are undefined, and their relationship is unclear.
Step-by-step explanation:
The question "How many RAC are there in 5 nocs?" doesn't provide enough context to give an accurate answer. RAC might stand for Reservation Against Cancellation, a term used in Indian Railways for ticketing, and 'nocs' could be a typographical error for 'nos' which is a short form for 'numbers'. If 'RAC' is meant to represent a measurable unit or quantity and 'nocs' is related to a count or number of those units, then further information is required to provide a conversion or relationship between the two. Without the proper context or definition of the terms, it's impossible to calculate an accurate number.
