Oh dear.
I am not sure what kind of weed you are smoking but a nuclear weapon is
the most destructive form of explosive out there. Your
underestimates are erroneous.
The 15 KT atomic bomb (Little Boy) - which was dropped over Hiroshima - killed 80,000 people in the city [immediately]. Among the survivors, 60,000 succumbed to significant injuries, burns and radioactive sickness some days later. Additional number of survivors (i.e. 40,000) died over the course of months. 200,000 people died due to Hiroshima-related incident by 1950.
Only very heavy masonry structures were standing after the explosion but
each suffered extensive damage and was not safe to inhabit afterwards. People inside these structures, also perished due to excessive heat, injuries and/or suffocation.
Urban areas contain many objects that can become airborne, and the destruction of buildings generates many more. The collapse of the structure above can crush or suffocate those caught inside. Serious injury or death can also occur from impact after being thrown through the air.

Roasted carcasses to say the least. And you think that people would be safe in them?

The blast
itself kills as many as it can, but the resultant blast wave travels much further and destroy much more accordingly. Radiation compounds the problem on top because it
infects everything from survivors to structures caught in the blast wave. Additional effects include numerous objects catching fires and EMP which will kill electronics and communications. And anybody who is foolish enough to explore the ruins and/or want to take a look from the immediate surroundings, would be risking radioactive sickness.
Destruction of the atomic bomb notwithstanding,
psychological implications would be severe. Back in the days of
World War II, people didn't knew much about the power and effects of atomic bombs; this is not the case today. A nuclear strike will trigger mass exodus of potential survivors from the affected city and its immediate surroundings due to the fear of radioactive contamination, non-functioning electronics and meltdown of services.
Now imagine 100 [
Little Boy type] nuclear weapons striking different parts of India. So many nuclear explosions - occurring in short order - will produce a new effect besides the usual stuff:
atmospheric poisoning.

India will seize to exist as a functioning economy and society; situation on the ground will be chaotic due to collapse of Law & Order, and survivors will fight each other for access to dwindling supplies.
Why do you think that your leaders are investing in BMDS programs? They understand the bigger picture: Pakistan have sufficient nuclear arsenal to ruin India.

Little Boy and
Fat Man were inefficient 1st generation single-stage fission solid core designs. US and USSR tested scores of nuclear weapons over the course of years, and have produced incredibly powerful and efficient designs with experience.
US tested a 2nd generation two-stage fission-fusion 15 MT hydrogen bomb in the
Bikini Atoll sector of the Marshall Islands in 1954 which contaminated 11,265 square KM with its radioactive fallout. FYI:

People are reluctant to go back to Marshall Islands even today:

Extreme yields are excellent for contaminating large portions of territory but do not necessarily make for an effective weapon against extremely hardened/deeply buried targets. Modern generation of nuclear weapons are about efficiency in design, accuracy in delivery and sufficient kinetic punch against high value targets; US have optimized its existing generation of nuclear warheads to achieve precision strikes and defeat extremely hardened/deeply buried targets with burst-height compensating
super-fuze modification.
