that is the entire purpose if TLB right?

Yes - but it is the other way. The TLB is tagged by page number, and the TLB entry contains the frame number. Benefit is that you don't have to go through a page table lookup.

page number and its corresponding frame number

That is what u meant by other way round right?

Yes yes yes. The distinction is important because you could be asked to calculate couple different things:

  1. Size of the TLB tag directory
  2. TLB Reach - this was just asked in Gate 2019
  3. Size of the TLB
  4. Overhead of the TLB

Ya
gate 2019 question was actually focused on how much u understand TLB rather than calculations

That question was good

When i first solved the paper I thought that each page must be accessed and I was wrong as actually they were looking for the word.

I started solving the question at blazing speed - converted VA to word-addressable, page size to words, calculated number of pages, as I read the question. Then realized all you had to do was multiply page-size in words with number of entries in TLB. Beautiful googly of a question.
