This site appears to contain a condensed (lol) version of copyright law for India:
TERM OF COPYRIGHT
Is copyright protected in perpetuity?
No. It is protected for a limited period of time.
What is the term of protection of copyright?
The general rule is that copyright lasts for 60 years. In the case of
original literary, dramatic, musical and artistic works the 60-year
period is counted from the year following the death of the author. In
the case of cinematograph films, sound recordings, photographs,
posthumous publications, anonymous and pseudonymous publications,
works of government and works of international organisations, the
60-year period is counted from the date of publication.
So, it looks like the answer is 60 years in India; but you should consult an expert (likely a lawyer, agent, or publisher) to ensure this is the right amount of time and that it is applicable to the work in question. In the U.S. this work you are looking at would be considered to be in the public domain and you could sell it exactly as is or tear it into the chunks you wanted.
